摘要
针对一非线性锅炉 汽轮机系统,提出了一种多变量滑模控制器的设计方法。为克服滑模控制的抖振现象,采用了边界层的方法。通过对输出的重新定义,消除了内动态子系统,实现了全局的稳定性。仿真结果表明,设计的控制器具有很好的跟踪性和鲁棒性。
A multivariableslidingcontroller is designedfora nonlinear boiler-turbine system. Toeliminate chattering in sliding mode control, a boundary layer around the switch surface is used. By means of redefining the system outputs, the internal dynamic subsystem is eliminated and the whole stability is achieved. Simulation results show that the designed controller has good abilities in tracking and robustness.
