Robust PI Controllers for Command Following with Application to an Electropneumatic Actuator

The problem of command following is studied for the case of linear systems with nonlinear uncertain structure and unknown disturbances. The problem is solved using an independent from the uncertainties PI controller. Sufficient conditions for the problem to have a solution are established. The appli...

Summary:The problem of command following is studied for the case of linear systems with nonlinear uncertain structure and unknown disturbances. The problem is solved using an independent from the uncertainties PI controller. Sufficient conditions for the problem to have a solution are established. The application of a robust PI controller for an electropneumatic actuator is presented. The effectiveness of the controller over a wide range of the system uncertainty is illustrated through simulation
