Dual-Channel Dynamic Event-Triggered Adaptive Output Feedback Control for Uncertain Nonlinear Systems

An adaptive dual-channel dynamic event-triggered control approach is proposed for uncertain nonlinear systems. This method introduces dynamic event-triggered mechanisms in both the sensor channel and controller channel to reduce data transmission. An observer is designed relying on the trigger output signal to estimate the unmeasured state. In addition, a dynamic filter is introduced in the backstepping design to avoid the direct differentiation of the virtual control law. Simulation results and analysis verify the efficiency of the suggested strategy.
