Abstract

A microprocessor-based multivariable controller incorporating state feedback as well as feedforward control for fast regulation and stability of a current source inverter-fed induction motor (CSI-IM) drive is presented. The design of the state feedback controller is based on the industrial regulator theory together with the pole-placement technique applied on a linearized d-q axes state-space model of the drive and includes a reduced-order observer to estimate the inaccessible states such as d-q axes rotor currents. A feedforward control in terms of reference and disturbance inputs has been added to the feedback controller-observer to obtain faster dynamic response. The controller is implemented in real-time using an Intel 8085 microprocessor kit. The hardware and software aspects of the controller are discussed, and test results are presented and compared with digital simulation results for step changes in references and load torque. Typical results show the possible improvement in response with the addition of feedforward control.<>

基于微处理器的具有状态反馈的CSI-IM驱动器前馈控制器

提出了一种结合状态反馈和前馈控制的基于微处理器的多变量控制器，用于电流源逆变感应电动机(CSI-IM)驱动的快速调节和稳定。状态反馈控制器的设计基于工业调节器理论，并将极点放置技术应用于驱动器的线性化d-q轴状态空间模型上，并包含一个降阶观测器来估计d-q轴转子电流等不可达状态。在反馈控制器-观测器中加入了参考和干扰输入的前馈控制，以获得更快的动态响应。该控制器采用英特尔8085微处理器套件实现实时控制。对控制器的硬件和软件进行了讨论，并给出了测试结果，并与参考值和负载转矩阶跃变化的数字仿真结果进行了比较。典型结果表明，加入前馈控制后，响应可能得到改善。
