用相平面法设计了一种基于变结构控制的固体KKV快速开关伺服系统,提出了用电动伺服系统实现大角度旋转阀门快速开关控制的应用方案,解决了无减速器电机直驱系统或小减速比伺服系统的大负载扰动问题。仿真分析与试验结果表明,该伺服系统具有较快的响应速度和较强的鲁棒性,对负载扰动具有较强的自适应能力。在带载条件下100°阶跃响应仅需13 ms,能满足大多数直接力开关控制系统的工程应用要求。所采用的相平面设计方法简单直观,设计的控制策略容易实现,具有较强的实用意义。
A kind of solid KKV fast switching servo system based on variable structure control was designed by phase plane method. The application scheme of electric servo system for fast switching control of large angle rotary valve was proposed, which solved the problem of direct drive system without gearbox or small deceleration Servo system than the large load disturbance problem. Simulation analysis and experimental results show that the servo system has faster response speed and stronger robustness, and has strong self-adaptability to load disturbances. The 100 ° step response under load conditions requires only 13 ms to meet the engineering requirements of most direct force switch control systems. The phase plane design method used is simple and intuitive, and the design control strategy is easy to implement, which has strong practical significance.
