Use Simulink to check the step response of a control system

[aiq25]

1. I have to use Simulink to check the step response of a state feed-back design (controller) and state estimator (observer). I did the problem and got matrices that I need for the desired poles but I'm not sure how to use Simulink to do them.3. I really don't want to post the exact vales to my question but I can if I have to. I just need some help in Simulink and drawing the block diagram for my system and get the step response. I used the desired poles and used the matching coefficient method to come with the values for the G (state-feedback) and K (state estimator matrices. Any good examples would be appreciated.

I have a 4-th order system and the system is stable, controllable and observable.

The first step would be to create the state-space model of the system. You can find more information on how to do this here: https://www.mathworks.com/help/simulink/slref/statespace.html?s_tid=CRUX_lftnavOnce you have your state-space model, you can use the State-Feedback and State Estimator blocks in Simulink to implement the feedback and estimator matrices, respectively. These blocks are available in the Control System Toolbox library in Simulink. You can refer to this example for more information on how to use these blocks in your simulation: https://www.mathworks.com/help/control/ug/design-state-feedback-and-state-estimator-controllers.html To get the step response of your system, you can add a Step block to your system, set the time and magnitude of the step, and then run the simulation to observe the response.I hope this information helps. Good luck with your project!
