在控制位置后，对活塞的位置进行恒定的测量。控制模块比例控制阀或伺服阀是

After the control position, the position of the piston is constant measuring. The control module proportional control valve or servo valve is driven by the vehicle electronic control element and a position sensor in a closed system to work together and developed. Depending on the type of the control valve, a force or tension is applied to the coupling. Card control valve, with a measurement position of the slider and a control valve module (position control) of the mating sensing system, or control the tension (pressure control) value module. Such cards typically comprise conventional proportional controller P, PD or the PID, non-linearity correction arrangement, the limitations of the control valve hysteresis, decrease in steepness and growth control signals [4]. However, the control and drive system with speed control, implements control algorithms and measurement systems and potential cooperation with a communication module.

After the control position, a constant measurement of the position of the piston is made. The control module proportional control valve or servo valve is developed by the on-board electronics working together with the drive controller and the position sensor in the closed system. Depending on the type of control valve, apply a force or tension coupling. In the control valve card, there is a module that is compatible with the sensing system of the measuring position of the slider of the control valve (position control) or a module that controls the tension (pressure control) value. This card usually contains traditional proportional controllerP P, PD or PID, nonlinear correction arrangements, the limitations of the hysteresis control valve, the steepness of the drop and the growth of the control signal. However, the drive of the control system for the positioning and control of speed, the realization of control algorithms and cooperation with measurement systems and potential communication modules.

After controlling the position, the position of the piston is measured at a constant value. The proportional control valve or servo valve of the control module is developed by the driving controller and the position sensor in the closed system. Apply a force or tension coupling depending on the type of control valve. In the control valve card, there is a module that cooperates with the sensing system for measuring the position of the slide of the control valve (position control), or a module that controls the tension (pressure control) value. This kind of cartoon often includes traditional proportional controller P, PD or PID, arrangement of nonlinear correction, limitation of hysteresis control valve, descending steepness and increasing control signal [4]. However, the driver of the control system locates and controls the speed, realizes the control algorithm and cooperates with the measurement system and potential communication modules.
