Question

Please provide an original answer. Will thumbs up. Thank you.

A position control system is given below. Use the MATLAB simulation tool (including Simulink) to design the controller and to select the appropriate parameters. Please document your source code (submit the code or Simulink block diagrams), show your simulation results, and provide an analysis of obtained results. You are allowed to work in groups of two students. d(t) r(t) yt) то Set d(t)-0 and then design the controller (select gains K, and K2) in order to provide a high-quality position control systems. Select a set of performance criteria and then examine the results of your design to check if the criteria are met 1. For such designed controller parameters in part 1, set r(t)-0 and determine the effect of the disturbance to the output y(t) 2. 3. Provide simulation results in a realistic scenario where r(t) * 0 (you can select an appropriate reference input) and where d(t) is a noise in the system.

Answer 1

ANSWER:-

BY USING MATLAB CODE:-

10 s3+10s2 Tanser Fon Step Gain LTI Sysem Soope LT ISystem 1 Display il

The controller is simulated to give the desired output equal to input. Step input with unit magnitude is taken as input and the output is obtained as 0.9992 with k1 = 0.01565 and k2 = -0.04.

2. When r(t) is 0 and disturbance input is active,

The disturbance signal is taken as white noise, The values of K1= 0.02792 and K2 = 10.

The output is

3.When both the inputs are active,

All the simulation is done to achieve input value at output.
