Abstract
In hydraulic systems driven by fast-switching solenoid valves, the utilization of conventional adaptive predictive controllers usually requires much computational effort, and thus it is difficult to realize real-time implementations in plants using short sampling times. This paper deals with an adaptive unified predictive controller which can be implemented conveniently for hydraulic systems driven by fast-switching solenoid valves. It is clarified by experimental investigation that the amount of computational effort is considerably reduced by employing the proposed controller. It is also clarified that the controller permits convenient and easy implementation of an adaptive predictive control scheme for on/off tracking control systems.
