Abstract

Abstract: Aimed at the problem of encoder fault of 3D stage wire system, combined with LADRC, two kinds of fault tolerant control strategiesare presented based on fault diagnosis reliability evaluation (FDRE) to prevent the spread of fault effects in the system and causing accidents. Based on this, the soft and hard smooth transition soft redundant switching mechanism is designed. The simulation results show that the control strategy can ensure encoder fault detection in a timely and reliable manner, and effectively improve the safety and reliability of 3D stage wire system.
