一种快速跟踪的模糊滑动模态控制方法的研究

The Study for a Kind of Fuzzy Sliding Mode Control which Can Quickly Track

根据滑动模态原理，将模糊控制系统的输入量简化为广义跟踪误差的一个超平面，该方法在隶属度划分上采用非线性划分，并针对一类仿射非线性系统作仿真，采用该方法，减小了系统到达滑动面时的“颤动”问题，同时在对非线性系统进行滑模控制中，采用根据误差信息，调整滑动面中的参数，结果提高了系统的跟踪速度，减小了跟踪误差．

：According to the principle of sliding mode, the inputs of fu zzy control system are simplified as an hyperplane of generalized trac king errors.The method adopts nonlinear partition in membership partit ion. Aiming at a kind of affine nonlinear system,we made emulation.Ado pting this method,we can decrease the chattering problem when the syst em gets to the sliding plane.At the same time,in the sliding mode cont rol for nonlinear system, we can increase tracking speed and decrease tracking error by adjusting parameters of sliding plane based on the i nformation of errors.
