良好的活塞式汽油发动机控制系统是小型无人直升机稳定飞行和保持恒定转速的前提条件。本文针对某型无人直升机发动机控制系统中采用的GV-1进行控制器参数的辨识,最后基于自抗扰控制技术设计出简单、可靠和成本低廉的转速控制器,实验结果表明,该控制器可以到达稳定飞行的需要。验证了所设计的控制器的有效性,可进一步简化小型无人机的转速控制,具有很好的应用价值。
A good piston petrol engine control system is a prerequisite for stable flight and constant RPM for small unmanned helicopters. In this paper, the controller parameters of a GV-1 used in a certain type of unmanned helicopter engine control system are identified. Finally, a simple, reliable and cost-effective speed controller is designed based on ADRC technology. The experimental results show that the controller Can reach a stable flight needs. Verify the validity of the designed controller, which can further simplify the speed control of the small UAV, and has good application value.
