摘要:

针对剪切风况下叶片多点静力加载中力耦合易引发结构共振和执行器饱和的问题,提出一种静力载荷超调控制方法。该方法利用离线标定的耦合系数矩阵求逆构建解耦矩阵,将多输入多输出系统转化为独立通道,切断施力牵连;设计积分分离与遇限削弱协同的抗饱和控制器,在大偏差时切除积分、饱和时依深度抑制积分累积,消除高频调节;引入递推最小二乘在线惯量辨识和基于目标变化率的前馈补偿,实时跟踪时变惯量并自适应调节增益、对目标突变进行超前补偿,从源头避免共振。实验表明:所提方法在80%极限设计载荷工况下,载荷跟踪均方根误差仅为1.1%,最大超调量降至2.1%,调节时间缩短至1.5 s;饱和能量比可降至2.7%;在线惯量辨识收敛时间小于3 s,稳态波动低于1.2%。该方法有效抑制了耦合共振与执行器饱和,实现了高精度、强鲁棒的多点静力载荷控制。

Abstract:

To address the problem of structural resonance and actuator saturation caused by force coupling in multi-point static loading of blades under shear wind conditions,this paper proposes an overshoot control method for static loads.This method constructs a decoupling matrix by inverting an offline-calibrated coupling coefficient matrix,thereby transforming the multi-input-multi-output system into independent channels and eliminating inter channel force interactions.An anti-windup controller integrating integral separation and saturation-depth-dependent integral suppression is designed,which removes integral action under large deviations and curbs integral accumulation according to saturation depth under saturated conditions,thus suppressing high-frequency oscillations.Furthermore,recursive-least-squares based online inertia identification and a feedforward compensation based on the target change rate are introduced to track time-varying inertia in real time with adaptive gain adjustment,and to provide leading compensation for abrupt reference changes,thereby avoiding resonance at its source.Experimental results demonstrate that under 80% of the ultimate design load,the proposed method achieves a root-mean-square tracking error of only 1.1%,a maximum overshoot reduced to 2.1%,and a settling time shortened to 1.5 seconds.The saturation energy ratio can also be reduced to 2.7%.The online inertia identification converges within 3 seconds,with steady-state fluctuation below 1.2%.This proposed method effectively sup-presses coupled resonance and actuator saturation,enabling high-precision and robust multi-point static load control.
