1 ME 352 System Dynamics and Control Homework #6 Due: Weds 27.04.2011 This is a personalized homework assignment. You will need to complete the following steps to construct your own blockdiagrams. s In your student ID number, collect digits x, y, and z. 2 x 0 7 0 5 0 y z s Compute a = x + y, b = z + 1, then keep numbers a and b. s Construct your own blockdiagrams by replacing numbers a and b by their values. [1]. Consider the following blockdiagram of a PID control system. Determine the optimal PID parameters using the Ziegler-Nichols process reaction method (by using MATLAB/Simulink). Obtain an open-loop unit-step response of your plant first. Give the resulting s-shaped unit-step response curve and your calculations on this curve. Find the optimal sets of controller parameters for P, PI, and PID. Give unit- step responses for these three cases of your closed-loop tuned system. Comment on the performance of

Unformatted text preview: your control system. Step Scope 1 (s+a)(s+b) Plant PID PID Controller [2]. Consider the following blockdiagram of a PID control system. Determine the optimal PID parameters using the Ziegler-Nichols ultimate sensitivity method. You can use either MATLAB/Simulink or analytical methods to find the ultimate gain. Increase the proportional gain until sustained oscillations are observed. Give the resulting response and show your calculations of the “ultimate period”. Find the optimal sets of controller parameters for P, PI, and PID. Give unit-step responses for these three cases of your closed-loop tuned system. Comment on the performance of your control system. Step Scope (s-1+j)(s-1-j) (s+a)(s+b) Plant PID PID Controller...
