including matlab code, It must includes step-by-step solution. 1. Analyze a given transfer function
G_(p)(s)=(k(s-a)(s-2))/(s(s+1)(s+0.1)(s+b))
such that
a
and
b
give the system stable using Routh-Hurwitz array. 2. A given function in Laplace transform
G_(p)(s)=(4(s^(2)+2s))/(s^(4)+3s^(3)+4s^(2)+6s+4)
a. Determine the step, impulse, and sinusoidal responses. b. Analyze the system is stable using Routh-Hurwitz array. c. Calculate amplitude ratio and phase angle. d. Use Ziegler-Nichols step-response method to determine PI controller e. Use Ziegler-Nichols frequency-response method to determine PID controller f. Simulate and compare closed-loop responses for both method. Determine, root mean square error (RMSE).
