摘要
大型机械臂等液压执行元件在驱动过程中由于负载平衡和结构等方面的原因,对同步控制的精度和响应速度要求较高。为实现大流量、高精度、高响应同步闭环控制,设计了高速开关阀为先导阀控制锥阀的同步回路。对系统进行了数学建模,利用MATLAB/simulink建立其仿真模型,并给出仿真结果。表明该同步系统具有响应速度快,同步精度高等优点,其同步误差控制在0.02mm以内。
The electro-hydraulic synchronizing control system of the large robotic arm such as high control accuracy and quick reaction speed is demanded.To achieve large-flow,high-precision,quick dynamic response of synchronizing closed-loop control,the report designs the high speed on/off valve is worked as the pilot valve for logical cone valve.A proper math-model was set up,by using the simulink toolbox in Matlab,the simulation model is established.The simulation result makes it clear that the synchronizing system has high accuracy and quick dynamic response.The synchronous error can be control within 0.02 mm.
