Parameter Uncertainties, Disturbance


This paper suggests a method of design and application of a robust controller able to suppress within specific limits the effects of control system parameters uncertainties, disturbances and noise. It also contributes to the analysis of system’s robustness by looking at its sensitivity in terms of all disturbing factors. The results of the system sensitivity in the frequency domain display the unique property of the designed robust controller, being effective for each case of parameters uncertainties, disturbances and noise. The performance of the robust controller is also assessed in terms of the system’s transient response.
