摘要
采用自适应模糊控制方法研究了死区补偿问题。通过引入系统当前状态与理想状态的归一化距离 ,构造了调节权函数 ,实现对模糊控制输入变量量化因子的自动调节 ,使得当系统处于死区时量化因子显著增加 ,使控制器的输出摆脱死区范围 ,形成对死区的自适应补偿。仿真结果表明该方法能够有效地提高系统稳态性能 。
The deadzone compensation using adaptive fuzzy logic is studied To implement self tuning scaling gains of the input fuzzy variables ,a weight function is constructed through defining a state distance from the ideal equilibrium point When the system is close to the stable state, the scaling gains notably enlarge and the adaptive deadzone compensation is accomplished.The simulation results show the proposed method can cancel out the deadzone effect and have not the oscillatory response
