Input resetting control (IRC) is an economical and effective approach to achieve good closed-loop behavior for systems with extra inputs. The paper investigates use of the cascade IRC implementation. A SIMC-based controller tuning rule is proposed for first-order plus time delay (FOPTD) processes in the two-input–single-output (TISO) structure. Satisfactory regulatory capacities for both set-point tracking and input resetting are obtained. Both of the controllers are analytically derived with proportional-integral (PI) forms by proposing the equivalent transfer functions. The resulting tuning guideline shows how the adjustable parameters should be changed to balance a trade-off between performance specifications and levels of robustness. Numerical simulations have been carried out to demonstrate the effectiveness of the proposed method. Moreover, the feasibility of implementing the proposed control strategy in practice is verified by a light intensity control experiment.

级联实现输入复位控制的双SIMC-PI控制器设计及其应用

输入复位控制（IRC）是一种经济有效的方法，可以为带有额外输入的系统实现良好的闭环性能。本文调查了级联IRC实现的使用。针对双输入单输出（TISO）结构中的一阶加时间延迟（FOPTD）过程，提出了基于SIMC的控制器调整规则。获得了对设定点跟踪和输入重置的令人满意的调节能力。通过提出等效传递函数，可以用比例积分（PI）形式对两个控制器进行分析性推导。最终的调整指南显示了应如何更改可调整的参数，以在性能规格和坚固性级别之间进行权衡。数值模拟已经进行，以证明所提出的方法的有效性。而且，
