As an ingenious concept which broadens the traditional error-feedback mechanism, the principle of self-support (PSS) is reviewed in this article with two extensions. Instead of regarding a control signal as an input variable or a cause of the control processes, PSS emphasized the independence and significance of the control signal in the whole dynamics. Moreover, due to nonlocal and history-dependent properties for fractional-order operators, many processes with memory and heredity can be well modeled by fractional-order systems, a pioneering work on the fractional-order generalized PSS (FOGPSS) is introduced. Meanwhile, motivated by the event-triggered schemes that enjoy benefits of reduced sampling efforts and better resource utilization, an event-triggered controller based on PSS is further presented. Finally, some future research directions are discussed in conclusion.

自支撑原理（PSS）及其分数阶微积分和事件触发方案的扩展


作为一个拓宽了传统误差反馈机制的巧妙概念，自支撑原理（PSS）在本文中进行了回顾，并进行了两个扩展。 PSS没有将控制信号视为输入变量或控制过程的原因，而是强调控制信号在整个动力学中的独立性和重要性。此外，由于分数阶算子的非局部和历史相关特性，许多具有记忆和遗传性的过程可以通过分数阶系统很好地建模，因此介绍了分数阶广义PSS（FOGPSS）的开创性工作。同时，在具有减少采样工作量和更好的资源利用率的事件触发方案的推动下，进一步提出了一种基于PSS的事件触发控制器。最后，对未来的一些研究方向进行了总结讨论。
