双电机驱动伺服系统的全系数自适应控制
ALL-COEFFICIENT ADAPTIVE CONTROL OF DUAL-MOTOR DRIVING SERVO SYSTEM
摘要
Abstract
Backlash nonlinearity and friction nonlinearity exist in dual-motor driving servo system, which reducing system response speed, steady accuracy and anti-interference ability. In order to diminish the adverse effects of backlash and friction nonlinearity to system, we proposed a new all-coefficient adaptive control method. Firstly, we introduced the dynamic model of backlash and friction nonlinearity respectively. Then on this basis, we established the characteristic model when backlash and friction nonlinearity coexist. Finally the all-coefficient adaptive controller was designed. The simulations of feed forward all-coefficient adaptive control and simplex all-coefficient adaptive control were compared, the results showed that the former has quicker response speed, higher steady accuracy, stronger anti-interference performance and better robustness, which validating the efficacy of the proposed control strategy.关键词
