摘要
提出了电流型逆变器-感应电动机(CSIM)传动系统的模型跟踪自适应控制系统,推导了离散形式的自适应模型跟踪控制系统的控制规律,这些规律在考虑负载和电机参数变化时满足超稳定性条件。建立了转差频率控制系统的动态数学模型,借助于模型降阶技术,在不显著降低系统性能的前提下,降低模型的阶数以简化设计。用一个8098实现了该控制器,控制系统的实现仅使用了参考模型和被控装置直接提供的状态量,无须辨识系统的内部变量,实验结果表明系统具有良好的性能。
An adaptive model following control system for CSIM is presented in this paper. Adaptive model following control laws in discrete form are derived. These laws satisfy the hyperstability condition for taking care of the load and machine parameter changes of the drive. A dynamic mathematical model of slip control based system is obtained. With the help of model reducing technique, full order model is reduced to simplify the design without degrading much of the performance. A microprocessor 8098 is used to develop the speed controller. The implementation of control system uses only available variables of reference model and controlled plant. Experimental results are given to demonstrate the good performance of the system.
