An electromagnetic actuator (EMA) represents a heartening approach to take the place of an imitative mechanical actuator system in plenty of workable applications. However, it is unlikely to be functional without achieving a successful execution by designing an active positioning-controller which can stabilize the system rapidly. In this work, a new analytical algorithm for the electromagnetic actuator (EMA) system has been developed. The proposed algorithm aims to generate well-suited reference position, velocity, coil current, and coil voltage profiles that rely on the initial and final states. Firstly, the reference position and velocity are shaped by a series of exponential functions with time as the independent variable. Then, initial and steady-state position, velocity, and acceleration conditions are automatically satisfied to ensure the required reference coil current and voltage. Eventually, extensive initial actuator position dispersions are considered to perform the presented approach using the Monte-Carlo simulation method. The demonstrated results show that the suggested algorithm strategy can greatly stabilize the electromagnetic actuator with a fast response and less overshoot in the presence of wide initial position dispersions.

This article focuses on the high-performance control of a high-response proportional solenoid valve which has two proportional solenoids. The valve is named high-response dual proportional solenoid valve (HDPSV). The HDPSV can achieve faster response than other high-response proportional solenoid valves with one proportional solenoid and has the potential of gaining stronger disturbance rejection due to the differential effect of two proportional solenoids. However, the expense for these advantages is that more complexity and more difficulties are involved in controlling the valve. In this article, the nonlinear dynamic model of the HDPSV is constructed first. The current–force gain of the proportional solenoid is modeled by a modified tanh() function to capture its nonlinear characteristics. An incremental differential allocation strategy is raised to coordinate the action of the two proportional solenoids driving the HDPSV. The model of flow force is built with parametric uncertainty and reconstructed to address its non-differentiability. To deal with the parametric uncertainties and uncertain nonlinearities appearing in the dynamic model of the HDPSV discontinuous projection-based adaptive robust control, which combines systematically backstepping adaptive control with deterministic robust control, is extended to synthesize HDPSV controller. Simulations and experiments are carried out to validate the effectiveness of the controller. Both the simulation and experimental results show that with the proposed adaptive robust controller, the flow forces are well compensated, while the HDPSV achieves disturbance rejection, high precision, fast transient response and broad bandwidth.

This paper considers a novel model predictive control method for a high-speed magnetic actuator. The actuator consists of two opposing electromagnets and an armature is suspended between them. The armature reciprocates between the two magnets. The armature is suspended by the springs with a large spring rate, enabling it to move at high speed. A difficulty is that push-pull control force for the armature is not available from the electromagnets. Additionally, magnetic force is effective only when the armature is very close to the pulling magnet. To overcome those difficulties, we propose a controller using model predictive control method with a fixed compensator. Based on optimality, the model predictive controller generates a target trajectory with searching for the terminal time, and a fixed compensator is attached in order to improve robustness drastically.
