| 中文摘要 |
| 针对电压源型逆变器供电的感应电动机调速系统,
提出了一种自适应逆控制方法, 实现了电磁转矩和定子磁链的解耦控制.
应用得到的逆系统将多变量、非线性、强耦合的感应电动机
调速系统解耦为电磁转矩和定子磁链两个一阶线性子系统,
从而简化了各个闭环线性调节器的设计难度. 为了提高系统的鲁棒性,
利用递推最小二乘算法实时辨识电动机参数,
降低了参数变化对系统性能的影响.
使用MATLAB软件进行了仿真实验, 实验结果验证了理论分析的正确性和控制方案的可行性. |
| 英文摘要 |
| The adaptive inverse
control strategies is presented for pulsewidth modulation (PWM)
inverter-fed induction motor drive system. The proposed control
strategies are then applied to obtain high performance decoupled
stator flux and torque control. Cascading the inverse system with
the drive sytem, the multivariable, nonlinear and strongly coupled
system is decoupled into two independent first-order linear
subsystems, or torque subsystem and stator flux subsystem, so as to
be easy to design the closed-loop linear regulators. In order to
enhance the robustness of the drive system, a recursive
least-squares method is also used for the identification of the
induction motor parameters. Finally, the control system is verified
with MATLAB simulations,
and the results are presented to show the validity of the adaptive inverse control strategies. |
