摘　　要：对交流电动机传动机械系统定速比控制问题进行了理论和试验研究，提出了定速比跟踪控制的策略和变结构前馈复合控制方法，介绍了定速比控制系统的构成。仿真和试验结果表明，控制方法具有鲁棒性和快速跟踪性，控制系统抗干扰能力强、可靠性好。对工程机械的定速比传动具有普遍的适用性和应用价值。The problem on the fixed velocity ratio control of mechanical systems with dualAC motordrives is investigated theoretically and experimentally.A tracking control strategy anda variable structure feedforward complex control approach is presented, and the constitutionof a fixed velocity ratio control system is introduced. The results of simulation and experi-ment indicate that this method has rubostness and a performace of fast-tracking, and the co-ntrol system has a high ability of frustrating disturbance and better reliability. This invest-igation will have a universal suitability and applicable value for the fixed velocity ratiocontrol of engineering machineries.
