双惯量系统振动抑制算法研究

双惯量谐振系统易发生低频机械振动,针对此问题,设计了一种基于Luenberger状态观测器的双惯量谐振系统振动抑制算法。根据双惯量谐振系统模型构造了系统的状态方程,并对其进行了离散化处理,在验证系统满足能观性条件的基础上,建立了用于观测双惯量系统负载转速和转矩的状态观测器模型。将实际模型与估计模型输出间的误差反馈至估计模型进行修正,使得状态估计值逐渐逼近实际值,进一步进行状态反馈控制,有效抑制系统机械振动。实验结果验证了设计的双惯量系统振动抑制算法的有效性和可行性。

Research on the Vibration Suppression Algorithm of Two-Inertia System

Two-inertia resonance system is prone to low frequency mechanical vibration.In order to solve this problem,a vibration suppression algorithm based on Luenberger state observer is designed.Based on the model of two-inertia system,the state equation of the system is constructed and discretized.On the basis of verifying that the system satisfies the observability condition,the state observer model for observing the load speed and torque of the two-inertia system is established.The error between the output of the actual model and the estimated model is fed back to the estimated model for correction,so that the estimated value of the state approximates the actual value gradually,and the state feedback control is further carried out to effectively suppress the mechanical vibration of the system.The experimental results verify the effectiveness and feasibility of the vibration suppression algorithm.
