3D刚体摆的倒立平衡点附近具有不稳定的流形,针对倒立平衡位置的姿态稳定性问题,建立T-S模糊模型,并采用并行分布补偿(PDC)法和线性矩阵不等式(LMI)法探讨了闭环T-S模糊控制系统的稳定性.仿真实验表明,T-S模糊控制对3D刚体摆倒立平衡位置处的姿态控制是可行和有效的.
Because of the unstable manifolds near the inverted equilibrium, for the attitude control problems at the inverted equilibrium position, T-S fuzzy model of the 3D rigid pendulum is modeled. Then by using the method of parallel distributed compensation(PDC) and linear matrix inequalities(LMI), the stability analysis of closed-loop T-S fuzzy control systems is investigated. The simulation results show that the T-S fuzzy control technique is feasible and effective.
