Abstract:
In order to further improve the calculation speed,control precision and stability of the nonlinear model predictive control,a controller design method based on the combination of Singular Value Decomposition Unscented Kalman Filter and Fast Ladder Predictive control is presented in this paper. Based on the Fast Ladder Predictive Controller,this method adds the Unscented Kalman Filter algorithm to reduce the noise interference and the control error. The controller design method is validated by the level control model of the three-tank water level. Simulation results prove that the method can improve the control precision and stability of the system under the noisy conditions,while ensuring the calculation speed.
