Dynamic Event-Triggered Output Feedback Control for a Class of High-Order Feedforward Nonlinear Time-Delay Systems

Global adaptive event-triggered output feedback control for p-normal feedforward nonlinear systems with uncertain output function

“…Literature [21] focused on the event-triggered issue of constrained nonlinear systems. Nevertheless, these results [17,18,19,20,21,22,23] can only ensure the boundedness of the CLS states. Thus paper [24] studied event-triggered output feedback control for nonlinear systems and ensured the convergence of systems states.…”

“…(ii) By constructing an appropriate adaptive law of dynamic gain and using the designed eventtriggering scheme, all the states of considered system asymptotically convergent to zero. Compared to literature [23], the dynamic gain in the trigger condition is removed, which will bring longer triggering interval. (iii) The nonsmooth event-triggered controller makes the existing approaches to prove the Zenofreeness infeasible.…”

Distributed Dynamic Event-Triggered Control to Leader-Following Consensus of Nonlinear Multi-Agent Systems with Directed Graphs

“…This control strategy has been widely applied to address consensus control in complex network systems and MASs with dynamics of different orders. Examples include first-and second-order dynamic models in [13][14][15][16], and higher-order models in [17][18][19]. There is no doubt that the choice of event-triggered strategy plays a decisive role in the performance of the system.…”

Global stabilization for a class of upper‐triangular stochastic nonlinear systems with input delay via sampled‐data output feedback

“…In addition, we should also notice that the existing sampled‐data literature 5‐25 only investigate the stabilization and tracking problems for the lower‐triangular nonlinear systems. However, for some engineering systems, such as the inverted pendulum systems, 26,27 they cannot be modeled as the typical lower‐triangular nonlinear systems, but can only be modeled as the upper‐triangular nonlinear systems, thereby the control studies for the upper‐triangular nonlinear systems also have strong engineering significance 28‐32 . Quantized feedback stabilization was analyzed in Reference 28 for an upper‐triangular nonlinear system with unknown output functions and coefficients; event‐trigger mechanisms were considered in References 29 and 30 for the considered feed‐forward nonlinear systems to solve their stabilization or tracking problems; finite‐time stabilization was discussed in Reference 31 for a non‐holonomic feed‐forward systems subject to inputs saturation; and a global sampled‐data output feedback stabilizer was constructed in Reference 32 for an upper‐triangular nonlinear system with improved maximum allowable transmission delay.…”

“…Further, the previous existing literature 5‐32 only focus on the sampled‐data studies for the deterministic systems, and we should also note that an engineering system is inevitable to be affected by the external stochastic disturbances, under this case, the engineering system can only be described as a stochastic nonlinear system 33‐40 . Fault‐tolerant controllers were constructed in References 33 and 34 for two stochastic nonlinear systems with full‐state constraints and input quantization; the switched stochastic nonlinear systems with time delay and output‐constrained were respectively analyzed in References 35‐37 to address the adaptive control problems; global adaptive control was realized in Reference 38 for a stochastic nonlinear system with unknown homogeneous growth rates; and observer‐based event‐triggered fuzzy control was discussed in References 39 and 40 for the stochastic nonlinear systems.…”
