Solenoids are presently used as cheap and robust switching components. These are variable reluctance devices with their characteristics dictated by a highly nonlinear magnetic circuit. This paper describes the research work done on converting a switching solenoid into a proportional device. It first investigates the magnetic characteristics of a solenoid, followed by developing a control model for the device. Based on this model, a dual rate cascade control scheme with a nonlinear force mapper is proposed for proportional control. This scheme is tested out by simulation and implemented on a Digital Signal Processor based controller.
