Abstract:In this paper, a dual-channel event-triggered quantized model-free adaptive control method for a three-degree-of-freedom helicopter attitude control system with limited communication resources is presented. First, the formulated dual-event triggering strategy integrates an input-triggered scheme and an output-triggered scheme to achieve semi-independent event-triggered control for the sensor-to-controller and controller-to-actuator channels, thereby further reducing communication frequencies. Second, a quantization mechanism is proposed to compress the control signals, thereby reducing the required communication bandwidth. Then, a dual-channel event-triggered quantized model-free adaptive control method is formulated, in which the accurate dynamics of the controlled helicopter are no longer needed. A stability analysis demonstrates that the control error of the controlled system is bounded by the designed method. Finally, the effectiveness of the proposed method is verified through simulation studies.
