Practical predictive non singular terminal sliding mode control based cascade control system

This paper presents a practical non singular terminal sliding mode (NTSMC) tracking control design for cascade system. The master loop controller is designed using the smith predictor and slave loop controller is designed using non singular terminal sliding mode control concept. Proposed strategies help to overcome the various causes by parametric uncertainties and external disturbances. The simulation results provide simplicity, robustness, and fast convergence against set point change and disturbance change which are compared with classical design approaches of cascade control system.
