Unmanned aerial vehicle and operation control method for same

Abstract

The invention provides an operation control method for an unmanned aerial vehicle. The operation control method includes steps of receiving flight state signals and judging whether the unmanned aerial vehicle flies according to suspension flight modes or not; outputting first control signals to a first motor by the aid of control branch circuits if the unmanned aerial vehicle flies according to the suspension flight modes, and outputting second control signals and third control signals to a second motor and a third motor by the aid of interface branch circuits; outputting fourth control signals to a fourth motor by the aid of the control branch circuits or the interface branch circuits. At least two of each first control signal, each second control signal, each third control signal and each fourth control signal have identical frequencies and identical phases; the control branch circuits comprise PLL (phase-locked loop) circuits, and the control signals can be outputted by the aid of output ends of the PLL circuits to at least one of the motors; the PLL circuits are connected with the interface branch circuits by switch paths of switch elements. The invention further discloses the unmanned aerial vehicle. The operation control method and the unmanned aerial vehicle have the advantage that the problem that an existing unmanned aerial vehicle is easy to shake when flying in steady fight states can be solved.

Description

technical field [0001] The invention relates to unmanned aerial vehicle technology, in particular to an unmanned aerial vehicle operation control method and an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicles refer to unmanned aerial vehicles that are controlled by infinite remote control technology and operate based on their own programs. UAVs have a long history in military use. In recent years, the field of use has gradually developed into the civilian field. It is widely used in aerial photography, agriculture, disaster relief and other fields, and is gradually expanding to express delivery. It has good commercial prospects. [0003] Four-axis UAV, also known as quadrotor helicopter, is a kind of UAV, which can realize various flight attitudes of vertical motion, pitch motion, and roll motion. The above-mentioned various flight attitudes control the work of the four motors through the CPU outputting four PWM signals. When the four-axis UA...
