- Abstract
- One of the main problems of Smith predictor control of time-delay processes is, that it does not handle the disturbances, especially in case the process has an integrator. In this case, the Smith predictor is not able to reset the steady state error. In this paper a modified Smith predictor control based on a variable structure algorithms for nominal controller and an approximate model for process is proposed. It is shown that the proposed method can assure the robustness of system even in presence of dead-time uncertainty.
