摘要
针对仿射多输入多输出非线性非最小相位系统,提出了一种新的镇定方案.用反馈线性化解耦系统输入输出关系,通过高增益状态反馈镇定系统外部动态,用模型预测控制镇定内部动态,所设计控制器能保证闭环系统的指数稳定性.仿真结果表明了所提出方法的有效性和优越性.
A novel stabilization scheme is presented for affine multi-input multi-output (MIMO) nonlinear non- minimum phase systems. The inputs-outputs of the system are decoupled by feedback linearization, and system external dynamics are stabilized by high-gain state feedback. Then model predictive control is used to stabilize internal dynamics. The proposed controller can guarantee that the closed-loop system is exponential stable. Simulation results demonstrate the effectiveness and superiority of the proposed method.
