4.37 Consider the process control system with the plant transfer function G(s) = &+0.4)(s+1.2)* (a) Design a PI controller such the rise time is less than 2 sec. (b) Design a PID controller so the system has no overshoot. (c) Design a controller such the peak time is less than 5 sec. 0.9

Explain the concept of Digital Twins in the context of IoT and its significance in modeling and simulation.

(a) Explain what PID control is. Describe how the coefficients of a PID controller will affect the system performance in terms of stability, transient response and steady-state error.

Discuss the role of VRMs (Voltage Regulator Modules) on a motherboard and their impact on CPU overclocking and stability.
