本文研究了具有输入和状态约束的非线性离散单调系统的跟踪控制问题。在先前设计的控制器上强制饱和通常可能导致不稳定，或者至少导致约束违反和性能损失。据此，它表明，对于某一类非线性单调系统，它是可能的设计一个静态非线性输出反馈，饱和之间的适当的状态依赖的界限，是能够保证约束满足和渐近跟踪分段常数参考，与一个温和的在线计算负担。蛋白质合成的仿真实验证明了所提出的控制策略的有效性。
This note addresses tracking control of nonlinear discrete-time monotone systems subject to input and state constraints. Forcing saturation on a previously designed controller may, in general, lead to destabilization or, at least, result in constraint violation and performance losses. Hereby, it is shown that for a certain class of nonlinear monotone systems it is possible to design a static nonlinear output feedback which, saturated among suitable state-dependent bounds, is able to guarantee constraint satisfaction and asymptotic tracking of piecewise constant references, with a moderate online computational burden. Simulation experiments concerning the synthesis of a protein demonstrate the effectiveness of the proposed control strategy.
