摘要
为了满足高精度随动系统的精度要求,以一种高精度伺服系统作为研究对象,建立力矩电机驱动的伺服系统的数学模型,采用超前滞后校正和提高增益、引入滞后环节的控制方法,对系统进行建模和仿真,实验结果表明,超前滞后校正的控制方法可以提高系统响应的快速性,满足高精度要求,提高增益、引入滞后环节的控制方法可以显著改善伺服系统死区非线性对于系统的影响。
In order to meet the accuracy requirement of the high accuracy servo system, this paper takes a high accuracy servo system as a research object and describes the establishment of the mathematic model of the servo system driven by torque motor. The control methods of lead-lag correction, gain improvement and lagging link are used to model and simulate the system. The simulation test results show that lead-lag correction control method can improve the response speed of the system and meet the high precision requirement, while gain improvement and the introduction of lagging link control method can reduce the im- pacts of the servo system dead zone nonlinearity on the system.
