【摘要】 研究非线性大系统的最优输出跟踪控制问题。针对大系统的二次型性能指标,提出了一种用级数近似方法设计次优控制率的方法。利用这种方法,高阶、耦合的非线性两点边值问题被转化成一族线性解耦的两点边值问题。截取最优跟踪控制律中无穷级数和的有限项得到次优跟踪控制律及其设计算法。仿真实例表明,该方法对非线性互连大系统最优跟踪控制律的设计是有效的。更多还原

【Abstract】 The optimal output tracking control problem for nonlinear large-scale dynamic systems is considered.A series-based approximate approach for designing the optimal controller is proposed with respect to quadratic performance indexes.By using the approach,the high order,coupling,nonlinear two-point boundary value problem is transformed into a sequence of linear decoupling two-point boundary value problems.By intercepting the frontal finite terms of the solution series,we obtained a suboptimal tracking control law.A simulation example illustrates the efficiency of the optimal output tracking control law designed.更多还原
