Consider a FKBC system in which the input u(t) only depends upon the error signal, e(t). Assume that the universe of discourse for the two variables are:-2 s e(t) = 2 and – 45 u(t) = 4. Let's design three types of linguistic variables for both the input and error signals as, positive (P), zero (Z) and negative (N). The membership functions of the error signal are shown below. N Z P -2 -1 0 1 2e The membership functions of the input signal are shown below. N uz P -4 -2 0 2 4 и
The fuzzy inference rules consist of the following three rules: Rule 1: If the error is positive (P), then the input is also positive (P). Rule 2: If the error is zero (Z), then the input is also zero (Z). Rule 3: If the error is negative (N), then the input is also negative (N). At time t, the measured error signal is given as e(t) = 1.0. Which one of following statements is true? A) Rules 1 and 3 will be fired. B) Rules 1 and 2 will be fired. C) Rules 2 and 3 will be fired. D) All the 3 rules will be fired
