摘要:
针对一类模型不确定的单输入单输出仿射非线性系统,设计一种使得闭环系统稳定且滚动 时域性能指标在线最小化的预测控制器。运用反演( Backstepping) 设计思想获得具有待定参数的 控制器表达式,其误差导数中的未知函数采用模糊逻辑系统来逼近,通过直接估计模糊系统最优参 数向量的范数上界来设计控制器和自适应律,大大降低了在线计算量。理论证明该方法设计的控 制器保证了闭环系统所有信号是半全局有界的,并且跟踪误差收敛于零的某一邻域。仿真算例验 证了所提出算法的有效性。

Abstract:
 Aiming at a class of uncertain SISO affine nonlinear system,a predictive controller which can make the system stable and can minimize an on-line receding horizon guaranteed cost was designed. By using backstepping technique the controller expression with undetermined parameters was acquired. With-in the design procedure,the fuzzy logic system ( FLS) was utilized to approximate the unknown function in error derivative. By directly estimating the norm bound of the FLS optimal parameter vector the control-ler and the adaptive laws were obtained,then the online computation complexity was reduced and the cal-culation was overcome. Theoretically,applying the controller proposed can guarantee that all signals in closed-loop system are semi-globally bounded and the tracking error converges to a neighbourhood of ori-gin. Finally,the simulation results demonstrate the effectiveness of the proposed control scheme.
