本文通过引入一个非线性补偿环节和一个开关量函数,解决了滞环非线性系统的自适应控制问题,并分别对滞环宽度已知和未知情况,建立了大范围渐近收敛和稳定的加权自适应控制算法.这种算法具有渐近最优的控制效果,能用于非最小相位系统.仿真结果表明,该算法具有良好的动态性能.
In this paper, by introducing a non-linear compensation and a switching function, the adaptive control problem of the hysteretic nonlinear system is solved. Asymptotic convergence and stable weighting of the hysteresis loop are established for unknown and unknown hysteresis width respectively Adaptive control algorithm.The algorithm has asymptotic optimal control effect and can be used in non-minimum phase system.The simulation results show that the algorithm has good dynamic performance.
