Discrete Sliding Mode Predictive Control of Networked Control Systems

This article studies the application of discrete sliding mode predictive control (SMPC) in networked control systems, introducing sliding mode control (SMC) into model predictive control (MPC), and prediction the state and output vector based on sliding mode control. By combining the strong robustness of sliding mode control and the advantage of model predictive control in dealing with communication constraints in network control, an incremental SMPC trajectory tracking control scheme based on a state observer is designed. The effectiveness and practicability of the designed control scheme is verified by tracking experiments on reference inputs in a dSPACE-based networked lighting control system.
