A design of electromechanical valve control system using model predictive controller

This paper considers an implementation of model predictive controller for an electromechanical valve. At each sampling time instants, the controller sends optimum control input to the system. In order to simplify the calculation process within controller, we solve the control input as algebraic calculation rather than two-point boundary value problem. We also use a disturbance observer to provide information of armature valve velocity, and to improve EMV robustness. The proposed control scheme is demonstrated on experimental testbed. The performance model predictive controller with a disturbance observer is compared experimentally to model predictive controller with a regular full order observer.
