A predictive control method of nonlinear systems

In this paper, an adaptive predictive control algorithm was presented for a class nonlinear system. Linear equation between increment output and input of nonlinear system was acquired by differential mean value theorem and time-variable parameters were identified by leakage recursive least squares algorithm. On the basis of fact, recursive state-space equations were used as predictive model and controller was designed by Linear predictive control theroy. The example of simulation results has shown the method´s validity.
