2. A negative feedback system has the plant transfer function $P(s) = \frac{1}{s(s+1)(s+9)}$. The control system has a PID controller with parameters, $K_p = 54$, $K_I = 51.4$, $K_D = 14.2$ Using SIMULINK determine the output response for given step input. 3. For the above PID controller problem determine the output response for given ramp input. 4. For the above PID controller problem determine the output response for given sinusoidal input.

Consider the second-order plant with the transfer function G(s) = 1 / ((s + 1)(5s + 1)) and in a unity feedback structure. (a) Determine the system type and error constant with respect to tracking polynomial reference inputs of the system for P [Dc = kp], PD [Dc(s) = kp + kDs], and PID [Dc(s) = kp + kI/s + kDs] controllers. Let kp = 19, kI = 0.5, and kD = 4/19. (b) Determine the system type and error constant of the system with respect to disturbance inputs for each of the three regulators in part (a) with respect to rejecting polynomial disturbances w(t) at the input to the plant. (c) Is this system better at tracking references or rejecting disturbances? Explain your response briefly. (d) Verify your results for parts (a) and (b) using Matlab by plotting unit-step and -ramp responses for both tracking and disturbance rejection.

Q4. A second-order system is underdamped with a damping ratio of 0.4 and a natural frequency of 10 Hz. Find a) the transfer function b) the time response when it is subjected to a unit-step input and the rise time. Hint: use the command stepinfo. Q5. Given the transfer function: G(s) = (s + 15) / (s + 100), find the peak time (Tp), percent overshoot (POT), and rise time (Tr). Q6. For the sinusoidal input u(t) = sin(10t) applied to the system: G(s) = (s + 2), determine the steady-state output of the system.
