现有的迭代学习控制研究关注于迭代学习控制系统在迭代批次方向的鲁棒收敛性,对控制系统在时间方向上的性能关注较少,没有展现出控制系统的动态特征。文中研究了有限频域范围线性连续重复过程在区域极点约束下的迭代学习控制问题。首先,结合二维系统理论,在时域中建立迭代学习控制系统的二维连续Roesser模型;然后基于Kalman-Yakubovich-Popov(KYP)引理,分析迭代学习控制系统的跟踪性能和区域极点约束问题;进而以线性矩阵不等式的形式给出控制器存在的充分条件,保证系统在批次方向和时间方向的性能,并将结果扩展到结构不确定性模型中;最后,通过典型的跟踪伺服系统执行机构的控制仿真验证了设计方案的有效性和可行性。

This paper develops new results on iterative learning control of a class of spatially interconnected systems for the particular case of the passive or active electric ladder *** task is performed by converting the problem to one of stability along the trial for a differential linear repetitive process,leading to design based on linear matrix inequality *** particular,sufficient conditions for the existence of a control law are developed together with the design algorithms for the associated controller *** this control law the resulting ILC dynamics have an asymptotic convergence in terms of an error sequence formed from the difference between both the distributed reference trajectory and the current trial output ***,an illustrative simulation is given to demonstrate the feasibility and effectiveness of the new designs.

For industrial batch processes with time-varying uncertainties, a robust output feedback based iterative learning control（ILC） design is proposed by introducing finite frequency specifications, based on only the output measurement. The integral of output tracking error in the time domain is incorporated into the ILC updating law to improve the tracking performance from batch to batch. Based on the generalized Kalman-Yakubovich-Popov lemma, robust stability of the resulting closed-loop ILC system along both time and batch directions is analyzed in the repetitive system framework. The corresponding ILC law can be determined from the established tractable linear matrix inequality conditions. Moreover, it is shown that the obtained stability condition can also guarantee the bounded output tracking error and system input in the presence of time-and/or batch-varying uncertainties. An illustrative example from the literature is adopted to demonstrate the effectiveness of the proposed design.

This paper proposes an improved PI based indirect-type iterative learning control for batch processes with timevarying uncertainties from a new perspective. The proposed ILC law can be designed independent of the initial PI tuning which primarily aims at holding the robust stability of the closed-loop system due to that only the setpoint command is adjusted by ILC. The feedforward control used in the recently developed indirect-type ILC methods is replaced by retuning the closed-loop PI controller, while the redundant learning information from the current and previous cycles could be reduced compared with the existing literature. Correspondingly, the control structure is significantly simplified with less design parameters, while achieving the similar convergence performance along the batch direction. A robust ILC updating law along with retuned PI parameters are derived by solving a linear matrix inequality and results in the robust stability of the closed-loop system. An illustrative example from the literature is adopted to demonstrate the effectiveness of the proposed method.

This paper deals with the problem of designing an iterative learning control scheme for uncertain time-delay systems using differential repetitive process stability theory. The resulting design produces a stabilizing feedback controller in the time domain and a feedforward controller that guarantees monotonic convergence in the trial-to-trial domain for all admissible uncertainties. The design procedures are delay dependent since the obtained results depend on the size of state delay and are also extended to limited frequency range design specification. A new design procedure is developed in terms of linear matrix inequalities, which guarantee prescribed performance specifications. Finally, a simulation example is given to illustrate the application of the new results.
