| 摘 要： | 针对一类典型的二阶振动系统,基于滑模控制理论研究了系统的控制问题。考虑系统存在不确定性的情况下,考虑不确定性上界已知和未知,分别设计了滑模控制器和自适应滑模控制器,并引入模糊控制消除滑模抖振的影响。最后通过仿真试验研究,验证了所设计控制方法的有效性。

| Abstract: | The decomposition and control of finite element modeling for two manipulators in handling a flexible payload were studied based on singular perturbation theory.The complex dynamic model of cooperative system was divided into a slow subsystem and a fast subsystem by dual-time scale transform.For the slow subsystem,when the bound of the uncertain was unknown,an adaptive fuzzy sliding mode controller was designed to realize system trajectory tracking performance.For the fast subsystem,considering the parameter perturbation,a robust optimal controller was presented to suppress the elastic vibration.Finally simulation results show the effectiveness of the proposed control scheme. |
