A three phase bridge inverter, From Figure.1, has 8 permissible switching states. Table I gives summary of the switching states and the corresponding phase-to-neutral voltage of isolated neutral machine. V B. Simulink Implementation To implement the algorithm in Simulink, we shall first assume that the three-phase voltages at the stator terminals must have the following from Equation. (1)-(3), the frequency f and the amplitude V are variables. However, the v/f control algorithm implies that there is a relationship between the amplitude of the voltage and the frequency, i.e. the ratio between the two quantities is constant.

FUZZY LOGIC CONTROLLER In drive operation, the speed can be controlled indirectly by controlling the torque which, for the normal operating region, is directly proportional to the voltage to frequency. The speed is controlled by fuzzy logic controller whose output is the reference current of the inner dc current controller. Fuzzy Logic control (FLC) has proven effective for complex, non-linear and imprecisely defined processes for which standard model based control techniques are impractical or impossible. Fuzzy Logic, unlike Boolean or crisp logic, deals with problems that have vagueness, uncertainty and use membership functions with values varying between 0 and 1. In fuzzy logic a particular object has a degree of membership in a given set, which is in the range of 0 to 1. The essence of fuzzy control algorithms is a conditional statement between a fuzzy input variable A and fuzzy output variable B. In general a fuzzy variable is expressed through a fuzzy set, which in turn is defined by a membership function. The torque is controlled by varying the dc current. The complete block diagram of the fuzzy logic controller is shown in figure 4 and The function of each block and its realization is explained below

3 resulting fuzzy inference system (FIS) is called a first order sugeno fuzzy model. Fig. 4 Block diagram of fuzzy logic controller A. Configuration of FLC It comprises of four principal components: A fuzzification interface A knowledge base A decision-making logic and A defuzzification interface. (a) Fuzzification Fuzzification interface involves the following functions. 1. Measures the values of input variable. 2. Performs the function of fuzzification that converts input data into suitable linguistic values (b) Knowledge base Knowledge base consist base and a linguistic control rule base. 1. The database provides necessary definitions, which are used to define linguistic control rules. 2. The rule base characterized the control goals and control policy of the domain experts by means of a set of linguistic control rules. (c) Decision making The decision-making logic is the kernel of an FLC. It has the capability of simulating human decision-making based on fuzzy concepts and of inferring fuzzy control actions employing fuzzy implication and the rules of inference in fuzzy logic. (d) Defuzzication Defuzzification interface performs the following functions. 1. A scale mapping, which converts the range of values of output variables into corresponding universe of discourse. 2. Defuzzification, which yields a non-fuzzy control action from an inferred fuzzy control action. B. Rules creation and inference In general, fuzzy systems map input fuzzy sets to output sets. Fuzzy rules are relations between input/output fuzzy sets. The modes of deriving fuzzy rules are based either of the following. Expert experience and control engineering knowledge. Operator s control actions. Learning from the training examples. In this thesis the fuzzy rules are derived by learning from the training examples. The general form of the fuzzy control rules in this case is IF x is Ai AND y is Bi THEN z =fi (x, y) where x, y and z are linguistic variables representing the process state variables and the control variable respectively. Ai, Bi are the linguistic values of the linguistic variables, fi (x, y) is a function of the process state variables x, y and the C. Fuzzy inference engine The function of the inference engine is to calculate the overall value of the control output variable based on the individual contributions of each rule in the rule base. (i.e.) the defuzzification process. There is no systematic procedure for choosing defuzzification. In first-order sugeno fuzzy model each rule has a crisp output and overall output is obtained as weighted average thus avoiding the time consuming process of defuzzification required in a conventional FLC. IV. DESIGN OF FUZZY PI CONTROLLER In drive operation, the speed can be controlled indirectly by controlling the torque which, for the normal operating region, is directly proportional to the voltage to frequency. The speed is controlled by fuzzy logic controller whose output is the reference current of the inner dc current controller. The torque is controlled by varying the dc current. The drive performance of SVPWM is improved by employing two sets of fuzzy logic controllers. From Figure 5 one set of fuzzy logic controller is used in the inner loop for controlling the torque of the motor which is proportional to DC link current Idc, and another set is used in the outer loop for controlling the actual motor speed. Fig. 5 Design of IM With FLC Architecture A fuzzy logic controller is proposed to control the speed of the motor to be constant when the load varies. The speed error e and the change of speed error ce are processed through the fuzzylogic controller whose output is the voltage command.current error is usually processed by current regulator to produce a control frequency. This control frequency adjusts the v/f of SVPWM such that the desired speed of the motor can be obtained. In the design of a fuzzy logic controller, seven membership functions were used for both error and change of error. Membership functions were constructed to represent the input and output value.as shown in Figure 7. The fuzzy logic controller consists of three stages: fuzzification, control rules evaluation and defuzzification. Therefore, the fuzzy logic controllers in the paper will result the higher accuracy in controlling the v/f. A fuzzy logic controller is proposed to control the speed of the motor to be constant when the load varies. The speed error and the change of speed error are processed through the fuzzy logic controller whose output is the voltage command I dc *

4 Fig. 6 Block diagram of fuzzy pi controller The current error is usually processed by current regulator to produce a control frequency ωe*. This control frequency adjusts the v/f of SVPWM such that the desired speed of the motor can be obtained. Consider the fuzzy speed control system, where the input signal are e(pu) and ce(pu) and the output signal is du, as explained before. Figure 7 shows the fuzzy sets and corresponding triangular MF description of each signal. The fuzzy sets are as follows :Z = Zero, PB = Positive Big, NB = Negative Big, PS =Positive Small, NS = Negative Small, Small, PM = Positive Medium NM = Negative Medium. The universe of discourse of all the variables, covering the whole region, is expressed in per unit values. All the MFs are asymmetrical because near the origin, the signals require more precision. There are seven MFs for e and ce signal, whereas there are seven MFs for the output. All the MFs are symmetrical for positive and negative values of the variables. Table 2 shows the corresponding rule table for the speed controller. The top row and left column of the matrix indicate the fuzzy sets of the variables e and ce, respectively, and the MFs of the output variable du are shown in the body of the matrix. There may be 7*7 = 49 possible rules in the matrix, where a typical rule reads as: IF ce is PS AND e is NM THEN du is NS.

RESULTS AND DISCUSSIONS To evaluate the performance of the system, a series of measurements has been accomplished.

VI. CONCLUSION This paper presents simulation results of fuzzy logic control for speed control of induction motor. In fuzzy control it is not necessary to change the control parameters as the reference speed changes, however with the classical PI controller this does not happens. With results obtained from simulation, it is clear that for the same operation condition the induction motor speed control using fuzzy logic technique had better performance than the PI controller, mainly when the motor was working at lower speeds. In addition, the motor speed to be constant when the load varies
