An adaptive predictive controller is proposed to solve the time-varying characteristics of the industrial process control system. The arithmetic of implicit expression generalized predictive control(IGPC) is put forward to compute the optimal control signal increment. In order to decrease the computing work and increase the computing speed, the system input/output data are used to identify the controller parameters directly and the plant model parameters are unnecessary. Simulation results show that the controller can track the change of setting value excellently even though without any prior information of controlled system, and have excellent adaptive abilities for the changes of system external disturbing signals and model parameters.
