【摘要】：目前有多种方式用来抑制调速系统中调节器饱和引起的Windup现象。其中跟踪反计算控制策略,由于其采用线性反馈作用原理来减小调节器饱和时的积分累加值,因此对于这种策略的研究和应用较多。但由于在设计调节器参数时,没有考虑速度指令和负载的变化,固定的反计算参数一般难以在大范围内保证系统响应的一致性。为了在不同速度指令和负载转矩条件下,保证系统响应的一致性,本文提出了积分状态预测Anti-Windup策略来减小系统由于饱和现象而引起的性能下降,根据速度指令和负载转矩的变化,在调节器饱和时计算出积分器在系统稳态积分终值,并将其作为调节器进入线性段的积分初始值,当系统参数精确时使得系统呈现出最优的速度响应曲线。本文在相同的电流环和速度环调节器PI参数的条件下,进行了仿真实验,比较了上述AW策略与传统方法的速度响应性能。实验结果验证了理论分析及仿真波形的正确性。
[Abstract]:There are Windup to inhibit control system regulator saturation caused by a variety of ways. The tracking control strategy because of its inverse calculation, using linear feedback principle to reduce the regulation of integral accumulator at saturation value, so the research and application of this strategy more. But as the regulator parameters in the design, did not consider speed and load changes, the inverse computation of fixed parameters in a large range is generally difficult to ensure the consistency of system response. In a different speed and load torque conditions, ensure the consistency of the system response, proposed integral state prediction Anti-Windup strategy to reduce the system due to the saturation phenomenon caused by the decline in performance, according to the speed and load torque change, calculate the integral in the steady-state value of the regulator is saturated, and as a regulator in line Some of the integral initial value, when the system parameters are accurate when makes the system response curve showing optimal velocity. In this paper, at the same speed and current loop PI regulator parameters, simulation experiments are carried out and compared the response performance of the AW strategy and the traditional method of speed. The experimental results verify the correctness of the theory analysis and simulation waveforms.
