Assignment 7
The Design of Feedback Control Systems

1. Watch video “EE495 – Week 7 – Lecture”
2. Read Chapter 10 in the text Modern Control Systems, 12th Edition.
3. Work the following problems:
   1. 1. A unity feedback control systems for a robot submarine has a plant with a third-order transfer function
    G(s) = K / (s(s + 10)(s +50))
   We want the overshoot to be approximately 7.5% for a step input and the settling time (with a 2% criterion) of the system be 400ms.  Find a suitable phase-lead compensator by using root locus methods.  Let the zero of the compensator be located at s = -15, and determine the compensator pole.  Determine resulting Kv.
   
   1. 1. A system of the form below with unity feedback has G(s) = K / (s + 5)2
   We desire the steady-state error to a step input to be approximately 5% and the phase margin of the system to     be approximately 45 degrees.  Design a lag network to meet these specifications.

Assignment 8
Digital Control Systems

1. Watch video “EE495 – Week 8 – Lecture”
2. Read Chapter 13 in the text Modern Control Systems, 12th Edition.
3. Work the following problems:
   1. 1. A closed-loop system has a hold circuit and process as shown below.  Determine G(z) when T = 1 and
    Gp(s) = 2 / (s + 2)
   
   1. 1. A sampled-data system such as that presented in problem (i) has a sampling period T = 0.05s and has
   G(z) = K (z3 + 10.3614z2 + 9.758z + 0.8353) / (z4 – 3.7123z3 + 5.1644z2 – 3.195z + 0.7408)
   
   • Determine K when the two real poles break away from the real axis.
   • Calculate the maximum K for stability.
