EEC 321: First Semester Continuous Assessment for EEC321 Control Engineering 1, Department of Electrical and Electronic Engineering, College of Technology, University of Buea, Instructor Dr Gerard Ombick, January 2026. Exercise 1: partial-fraction expansion and time-domain response of two given Laplace-domain functions, with initial/final value theorem checks, using a printed Laplace transform-pair reference table. Exercise 2: finding the transfer function R(s) to Y(s) of a multi-loop block diagram (six forward-path blocks G1-G6 and three feedback paths H2-H4) via block-diagram algebra or Mason's rule. Exercise 3: finding the error constants Kp, Kv, Ka for a unity-feedback system with open-loop transfer function (s+1)/(s^3+s^2). Exercise 4: for a classic second-order position-control system, finding the gain K giving a damping ratio of 0.4 after adding minor-loop feedback, and comparing overshoot/rise time/peak time/settling time before and after.
