Abstract

The invention discloses an unmanned helicopter flight control system which comprises an onboard unit and a ground control station unit. The onboard unit comprises a flight control computer, a sensor module, a servo control module, a wireless transmission module, a remote-controlled receiver and an actuating mechanism. The ground control station unit comprises a measuring and controlling terminal having a wireless transmission function; the measuring and controlling terminal comprises a PC (personal computer) console and a remote control. The system comprises an automatic control mode and a manual control mode and has the advantages of being small in size and light in weight. The invention further discloses a control method of the unmanned helicopter flight control system, and the method includes that output quantity is calculated and controlled by a closed-loop control algorithm to control the actuating mechanism to operate. By the method, complexity in manipulating a model helicopter is reduced, and the helicopter is enabled to have the basic capacity in automatic flight. Therefore, quite good society and economy benefits are achieved.

Description

technical field [0001] The invention discloses an unmanned helicopter flight control system and a control method thereof, and belongs to the technical field of autonomous control of remote-controlled model (unmanned) helicopters. Background technique [0002] The remote control model helicopters currently on the market work in the signal direct way, that is, the operator sends out a signal by controlling the handheld remote control, and the receiver installed on the helicopter directly drives the steering gear and the motor after receiving the signal, and changes the main signal by changing the pulse width. Rotor speed and swashplate position, and then control the helicopter according to the remote control. Some helicopters are also equipped with onboard gyroscopes, which can increase certain damping and facilitate control. [0003] This manual working method is simple and convenient, but it brings a problem: the remote control model helicopter is difficult to control, and ...
