摘要

针对矿井通风机倒机过程中存在的执行器饱和问题,将变结构PID抗饱和控制与非线性自适应控制相结合,设计了自适应PID抗饱和控制器。基于带死区的投影算法建立矿井通风机倒机过程线性和非线性模型;针对这2个模型,分别设计一个变结构PID抗饱和控制器;计算线性和非线性自适应PID抗饱和控制器在不同状态下的运行评价指标,选择评价指标值较小的控制器用于该状态下的矿井通风机倒机过程控制。仿真结果表明,自适应PID抗饱和控制器能够保证井下传输风量的平稳,很好地解决了执行器饱和问题。
        In view of actuator saturation problem in switchover process of mine ventiliator,an adaptive PID anti-saturation controller was designed based on combination of variable structure PID anti-saturation control and nonlinear adaptive control.Based on the projection algorithm of dead zone,the linear and nonlinear models of switchover process of mine ventilator were established.A variable structure PID antisaturation controller was designed respectively for the two models.The operation evaluation indexes of linear and nonlinear adaptive PID anti-saturation controller in different states were calculated,and the controller with smaller evaluation index value was selected for the switchover process control of mine ventilator in this state.The simulation results show that the adaptive PID anti-saturation controller can ensure smooth transmission of underground air volume and solve the problem of actuator saturation.
