a) b) A fuzzy controller utilises three processes which include fuzzification, inference and de- fuzzification. Explain the requirement and operation of each of the three processes. 19 marks) The inputs to a fuzzy P+D controller are given as error and rate of change of error. The controller output is in the form of voltage. Sketch typical input and output membership functions (maximum of three for each input and output) supported by a fuzzy association map describing the rule base. [6 marks) c) The inference engine within a fuzzy controller has produced the following output memberships. 1 1.1 1.2 2 2.1 2.2 2.4 2.7 5 V Figure Q5c Calculate the crisp output voltage using an appropriate method.
