快速反应的电磁阀的研究促使液压系统直接数字控制更为可行,但对使用这种阀并用常规控制技术进行负载位置的精确控制仍然是一个难题。其理由是:开关控制器需要完善的线路以控制负载位置并避免超调、失调和不稳定。如果具有合适的控制对策的一个微处理机加入到上述阀控系统则问题能够获得解决。 Rapid response solenoid valve research has led to direct digital control of hydraulic systems more feasible, but the use of such valves and conventional control techniques for accurate control of load position is still a challenge. The reason is that the switch controller needs a complete line to control the load position and avoid overshoot, offset and instability. The problem can be solved if a microprocessor with a suitable control strategy is added to the above valve control system.
