Research on load simulation control system based on optimal H∞ method

Abstract

Abstract In order to optimize the accuracy of the vehicle load simulation system, the control framework of the system is established based on the speed tracking method. Based on H∞ mixed sensitivity method, a disturbance observer is established. In order to solve the problem that the order of disturbance observer is too high to restrain disturbance directly, a design constraint framework of disturbance observer is proposed, and the optimization of disturbance observer is realized in the constraint framework. The simulation and experimental results show that the optimized disturbance observer has stronger disturbance rejection ability.
