Abstract
This paper studies the event-triggered control (ETC) of the nonstrict-feedback nonlinear system with unknown measurement and unknown model dynamics, where the output function \(y=h(x_1)\) is uncertain and nonlinear. The radial basis function neural networks (RBF NNs) are utilized to compensate for the packaged uncertainties including \(x_1-h(x_1)\). An event-triggered state observer is established to achieve the output-feedback control. The observer-based control design is thereby carried out following from the backstepping method. With two levels approximating structures, the problem of “algebraic loop” is overcome by using the property of the basis function. It should be noted that the ETC works in the sensor-to-controller (SC) channel. While it is combined with backstepping, the consequent problem called “jumps of virtual control laws (JVCL)” [1] is solved by introducing the average dwell time (ADT) technique. A composite triggering condition with the dead zone is constructed to guarantee the semi-globally uniformly ultimate boundedness (SGUUB) of all the errors, as well as to avoid the “Zeno” behavior. Three numerical examples verify the effectiveness of the proposed scheme.
