New Discrete Predictive Sliding Mode Control for Non Minimum Phase Systems

Abstract

This paper shows the development of a Predictive Sliding Mode Controller (PSMC). The proposed controller blends the design of Sliding Mode Control (SMC) with Model Predictive Control (MPC). The combination of SMC and MPC improves the performance of these two control laws. The designed control strategy has stronger robustness and chattering reduction property to conquer within the system uncertainties. The Predictive Sliding Mode Control strategy was improved by giving a New Predictive Sliding Mode Controller (NPSMC). Finally, the performances of the NPSMC, in terms of strong robustness to external disturbance and parameters variation, chattering elimination, fast convergence were judged, in comparaison with PSMC, SMC and MPC, using a nonminimum phase system.
