Consider industrial automatic controllers whose control actions are proportional, proportionalplus- integral, proportional-plus-derivative, and proportional-plus- integral-plus-derivative. the transfer functions of these controllers can be given, respectively, by ((*) ,(*) = kp ((*) ,(*) = kp (1+ - ./ * ) ((*) ,(*) = kp (1+ td s ) ((*) ,(*) = kp (1+ - ./ * + td s ) where u(s) is the laplace transform of u(t), the controller output, and e(s) is the laplace transform of e( the actuating error signal. sketch u(t) versus t curves for each of the five types of controllers when the actuating error signal is: (a) e(t) = unit step function (b) e(t) unit ramp function in sketching curves assume that the numerical values of kp, ki, ti, and td are given as: kp = proportional gain = 4 ki= integral gain =2 ti = integral time =2 sec td = derivative time 0.8 sec

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
