摘要
不同工况引起加载力之间的耦合效应降低了速度控制效果,为了更加精准控制不同工况下的主轴速度,提出一种多工况下的液驱多维力加载装置主轴速度控制方法。计算多工况下的液驱多维力加载装置主轴速度,以此作为控制器设计输入。在多种工况下,将液驱多维力加载装置主轴输入和输出速度之间的差值作为输入信号,通过模糊推理算法改进经典PID控制器,通过模糊检测调整改进后的控制器组建模糊自适应PID控制器,实现速度自适应控制。通过实验测试证明,所提方法可以精准地完成液驱多维力加载装置主轴速度控制,受工况影响较小。
The coupling effect between loading forces caused by different working conditions reduces the speed control effect.In order to more accurately control the spindle speed under different working conditions,a multi working condition hydraulic drive multi-dimensional force loading device spindle speed control method is proposed.Calculate the spindle speed of the hydraulic multi-dimensional force loading device under multiple operating conditions,and use this as the input for controller design.Under various working conditions,the difference between the input and output speeds of the spindle of the hydraulic drive multi-dimensional force loading device is used as the input signal.The classical PID controller is improved through fuzzy inference algorithm,and the improved controller is adjusted through fuzzy detection to form a fuzzy adaptive PID controller,achieving speed adaptive control.Through experimental testing,it has been proven that the proposed method can accurately control the spindle speed of the hydraulic drive multi-dimensional force loading device,and is less affected by operating conditions.
