| 中文摘要 |
| 针对采用极点配置的自适应速度观测器存在不稳定区域的问题, 建立了全阶自适应状态观测器并给出了观测器的速度辨识律. 应用Lyapunov 稳定性理论, 观测器的增益借助于MATLAB LMI工具箱求解两个双线性矩阵不等式得到. 在MATLAB 6.5/SIMULINK环境下, 建立了无速度传感器感应电机直接转矩控制的仿真实验平台, 给出了无速度传感器直接转矩控制的仿真结果. 仿真结果表明本文给出的自适应观测器在全速范围内具有很好的稳态性能, 并具有很好的鲁棒性. 同时, 在以TMS320F240 为核心的感应电机直接转矩控制系统上进行了速度辨识实验, 实验结果验证了方案的有效性. |
| 英文摘要 |
| To deal with the unstable problem of the adaptive speed observer using pole-placement technique, a fullorder adaptive state observer is created and a speed identification law is proposed based on the observer. By using the Lyapunov stability theory, the gain matrix of the observer is obtained by solving two bilinear matrix inequalities in Matlab LMI toolbox. The simulation scheme of speed control for a sensorless induction motor using direct torque control is built in the Matlab6.5/Simulink. Simulation results indicate that the proposed observer has good steady performance and good robustness. The speed estimation experiment is implemented in the direct torque control system of induction motor based on TMS320F240. Experiment results show the feasibility of the scheme. |
