摘要
文中提出了一种滑模控制方法,并将其应用在无杆气缸气动执行器的位置控制中。首先对气动伺服系统进行建模;然后设计了滑模控制器,其中用饱和度函数代替符号函数以减小抖振;最后对气动位置伺服系统进行仿真和试验研究。结果表明:与PID控制相比,这种方法不但具有较强的鲁棒性,而且跟踪效果良好。
In this paper,a sliding mode control method which combines with boundary saturation function for pneumatic servo is presented.Compared with PID control,the method can climinate the chattering efficiently and has more robustness and tracks a class of nonlinear systems accurately in the presence of disturbances and parameter variations.The simulation result demonstrates the effectiveness of the method.
