QUESTION 3 Consider a unity negative feedback control system. Assume that the plant G(s) does not have an integrator and you are using a proportional compensator K. You want to increase the closed-loop step tracking performance. Currently, the steady- state tracking error of the closed-loop system with K=K_old to a unit step signal is 0.1. You would like this error to be reduced to 0.02 with a new proportional compensator K=K_new. How does the proportional gain have to change to make this possible? We assume that the closed-loop is stable for all values of the proportional gain. Do not guess as incorrect answers will incur a penalty.

Q:: Read each statement carefully and answer by True or False (if False then, correct the statement). 1- Decrease the derivative time to reduce the effects of noise on feedback. 2- In the process systems, the integrator variables are always to be controlled because the integrators are unstable. 3- It is required to do a data validation before proceeding wiun une vmp.. modelling procedure. 4- Without a measurement filter, the noise does not go "around and around" in the feedback loop. 5- Feedforward control affects the stability of the Feedback control system when they are used together. 6- The statistical method has more calculations than process reaction curve method IIl when finding the empirical model.

QUESTION 16 Consider a unity negative feedback control system. It is assumed that the plant G(s) includes an integrator and you are using a proportional compensator K. You want to increase the closed-loop ramp tracking performance. Currently, the steady-state tracking error of the closed-loop system with KK_old to a unit ramp signal is 0.1. You would like this error to be reduced to 0.025 with a new proportional compensator K=K_new. How does the proportional gain have to change to make this possible? We assume that the closed-loop is stable for all values of the proportional gain.
