摘要
工业发展的要求使得双(多)电机的运用越来越广泛。双电机同轴驱动的控制系统是一种典型的多通道多控制器系统,为了获得优良的控制性能,有必要对其控制器参数的整定进行研究。采用单弹簧-双惯量块模型对系统进行建模后,首先采用传统遗传算法,对多通道多控制器系统的控制器参数进行整定;然后从系统整体性能的角度出发,利用带精英策略的非支配排序遗传算法对系统控制器参数进行多目标整定。仿真结果表明:采用双通道联合整定,可以获得比采用单通道独立整定更好的控制效果;采用带精英策略的非支配排序遗传算法对多目标和多通道多控制器系统的控制参数整定,可以使双电机同步驱动系统获得良好的动态和同步性能。
With the rapid development of industry, dual/multi-motor control has been applied extensively. In order to achieve excellent performance , it is necessary to study the tuning of the multi-channellcontroller parameters, which is typically used in dual coaxial drive motor system. It modeled the system with single spring and double inertia blocks. And using traditional genetic algorithm, the control parameters of the multi-channel^controller system were tuned. Then considering the overall performance of system, a method to tune control parameters has been proposed using Non-Dominated Sorting Genetic Algorithm-II （ NSGA-II ）for multi-objective system. Simulations show that the method to tune dual-channel together can accomplish better performance than that of single-channel separately. Besides, it also illustrates that the application of NSGA-II allows dual-motor synchronous drive system the satisfying dynamic and synchronization performanee in the case of tuning for the multi-obiective and multi-channellcontroller system.
