高速开关阀控制的电液式节气门执行器

研究了一种利用高速开关阀对节气门进行电子控制的系统方案。使用电液式执行器作为节气门控制的执行机构，利用高速开关阀对执行器进行连续的流量控制。建立了控制系统的数学模型。关于高速开关阀的开启时间所引起的精确定位问题，通过在控制器中加入非线性补偿环节的方法予以补偿。文中还对节气门位置控制中，被控对象的主要影响参数进行了讨论。数字仿真和装车道路试验，证明了该控制系统的实用性和可行性。

Electronically-controlled Hydraulic Throttle Actuator with High Speed On-off Valve

This paper develops the control system of electronically controlled throttle with high speed on off valve.The electronically controlled hydraulic actuator is used to control the throttle controlled by high speed on off valve.The mathematical model of the control system is established.Because of the existing turn on time of high speed on off valve,the problem which throttle position is controlled actuately is solved by adding a nonlinear compensating block.Main parameters affecting throttle position control are discussed.Simulation research and road test prove that the control system is applicable and feasible.
