A new result on semi-synchronous event-triggered backstepping robust control for a class of non-Lipschitzian networked systems
作者：
Highlights：
• Compared with design methods in related results, the novel piecewise constant virtual control signals are designed and the requirement of designing a differentiator is avoided. Thus, the backstepping method in this paper is more suitable for networked control systems.
• A semi-synchronous event-triggered scheme is designed. Compared with some conventional event-triggered schemes, the triggering instants among the channels are largely staggered to reduce network congestion; A self-triggered scheme is further proposed to avoid the continuous monitoring of the event-triggered conditions.
• Compared with some switching methods, the constraints of ADT are canceled to allow more frequent switchings.
• A class of nonlinear systems with Hölder condition and linear growth condition is introduced, such that the robustness of the proposed backstepping method is extended.
