The following questions refer to a fuzzy control systems. (a) What is the effect of increasing the number of fuzzy sets on the accuracy of the control. (b) Using the standard (Mamdani's) implication, is the truth values of the rule "If x is LO then y is HI" the same as that of "if x is LO and y is HI"? Explain. (c) In what situations is fuzzy control superior to the conventional control? Explain briefly. (d) Comment on the validity of the following statement: "A fuzzy PI-like controller is obtained by fuzzifying e, determining u = k,e+k, fedt and then defuzzifying u."
