Abstract

The paper presents the predictive control method with soft state constraints to increase the optimization of the nonlinear system. The method applied to a unactuated system as the crane system for precise position control and load anti-swing. Simulation results on Matlab is compared to PID control methods and have demonstrated the effectiveness of the method for multiple input - multiple output nonlinear systems.
