Consider a unity feedback system with the plant Gp(s) and the Gc(s). PID control action is applied to the plant s + 10 Gp(s) = 7 (s + 1)(s + 2)
The PID controller has the transfer function obid
Ge(s) = Kp ( 1 + 1/ s + Tos) Use the values T = 0.2 and Tp = 0.5. noves
a. Identify the open-loop poles and zeros.
b. Identify the root locus parameter K in terms of Kp. c. Identify the closed-loop poles and zeros for the case Kp = 10.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
