This paper assesses the tracking problem of fractional-order nonlinear systems by introducing new event-triggered control designs, which include two adaptive fault compensation event-triggered schemes and propose static and dynamic event-triggered strategies. It is demonstrated that the Zeno phenomenon is strictly avoided in the proposed control methods.
The tracking problem of the fractional-order nonlinear systems is assessed by extending new eventtriggered control designs. The considered dynamics are accompanied by the uncertain strict-feedback form, unknown actuator faults and unknown disturbances. By using the neural networks and the fault compensation method, two adaptive fault compensation event-triggered schemes are designed. Unlike the available control designs, two static and dynamic event-triggered strategies are proposed for the nonlinear fractional-order systems, in a sense that the minimum/average time-interval between two successive events can be prolonged in the dynamic event-triggered approach. Besides, it is proven that the Zeno phenomenon is strictly avoided. Finally, the simulation results prove the effectiveness of the presented control methods. (C) 2021 The Franklin Institute.
