Predictive control based on wavelets of second-order linear parameter-constant distributed parameter systems

As the complexity of distributed parameter system, there are still problems to build up accurate model of it and to control the system. A new method about the predictive control of distributed parameter system is introduced in this paper. Based on orthogonal wavelets, second-order linear parameter-constant distributed parameter system is approximated so that the distributed parameter system has been converted to lumped parameter system. Similarly on orthogonal wavelets, predictive control algorithm of time-discrete distributed parameter system is proposed in this paper. Haar wavelets is applied to the predictive control of this DPS. Simulations when system control parameters change, equation parameters vary and system output disturb occur are presented. The simulation results have verified the presented algorithm.
