摘要
提出了基于压差传感的进、出口节流独立调节原理 ,特别适用于大惯性负载的加、减速及制动过程控制。理论分析和试验表明 ,采用该调节原理 ,可以缩短大惯性负载加速过程时间 ,避免减速及制动过程中执行器出油侧的压力冲击 ,提高系统的阻尼比 ,是改善大惯性负载加速特性、解决大惯性负载减速及制动过程平稳性问题的有效途径之一。
A meter in,meter out independent regulated control principle based on pressure decrease sensing is advanced,which could be applied in the control of acceleration,deceleration and brake process of high inertia loads.Results show that acceleration process of high inertia loads is shortened,the large pressure clash in the outlet side of actuator could be avoided and the damping ratio of the system could be increased in deceleration and brake process of high inertia loads after this principle is adopted.It is an efficient way to solve the smoothness problem of deceleration and brake process of high inertia loads.
