    摘 要:风洞调速系统在不同转速下的负载变化较大,这给电机控制算法带来了极大挑战。针对风洞调速系统稳态运行速度控制精度高,及动态运行姿态调整速度超调小的要求,设计了一种参数自适应控制的调速系统。建立转速控制模型和风洞负载模型,分析风洞负载速度控制不能全速范围使用一组调节器参数的问题。在此基础上,引入当前速度,针对性的设计不受工况限制的自适应速度闭环控制。仿真结果表明,设计的基于参数自适应的速度闭环的控制系统,在满足稳态控制精度的同时,速度动态变化时几乎无超调,可以使一组控制器参数满足不同工况的速度控制性能。

    Abstract: The load of the wind tunnel speed regulation system varies greatly at different speeds, which poses a great challenge to the motor control algorithm. In response to the requirements of high steady-state operation speed control accuracy and small speed overshoot during dynamic operation attitude adjustment in the wind tunnel speed regulation system, a speed regulation system with parameter adaptive control has been designed. Establish a rotational speed control model and a wind tunnel load model, and analyze the problem that a set of regulator parameters cannot be used throughout the full speed range for wind tunnel load speed control. On this basis, the current speed is introduced and a targeted adaptive speed closed-loop control that is not restricted by working conditions is designed. The simulation results show that the designed speed closed-loop control system based on parameter adaptation not only meets the steady-state control accuracy but also has almost no overshoot when the speed changes dynamically, enabling a set of controller parameters to meet the speed control performance under different working conditions.
    Key words: wind tunnel speed regulation; asynchronous motor; parameter adaptive control; steady-state accuracy; speed overshoot
