【摘要】 为满足调平系统对快速性和准确性的要求,提出了应用于调平系统的Bang-Bang变结构控制算法,同时给出了切换线参数的配置原则;针对固定切换线的Bang-Bang控制对变化的负载控制能力弱的特点,提出了模糊自适应变切换系数的方法,降低了系统在切换线附近的抖振,同时提高了系统的调平速度。对比调平系统中普遍采用的PID控制方法,该方法仅需调节一个参数,降低了参数整定的难度。仿真和实验测试表明该方法是稳定的、简单的和有效的。更多还原

【Abstract】 Consider the precision and rapidity problem of leveling systems,propose a Bang-Bang variable structure control algorithm on leveling systems,and a configuration principle of switching line is given.A fuzzy control strategy is added to the Bang-Bang variable structure control,which weakened the chattering near the switch line and reduced the leveling time.Only one controller parameter needs to adjust by using this method instead of three parameters to adjust by using PID control law.Simulation results show that this controlling method is rapid,stable and easy using.更多还原
