| Quadrotor helicopter is light and very agile which attracted much attention of scientists. This article present the development of quadrotor helicopter research status overseas and domestic. Also introduced the basic principle of the quadrotor helicopter movement. Focused on the fly control circuit.With the Continuously improve of the power consumption, speed and Peripheral resources of Microcontroller, The traditional MCU has been unable to meet the require of many devices. STM32F103 series chip put ARM Cortex-M3 kernel to use. It is Low power consumption, ultra high speed. The STM32F103V series chip has 100 pins, a large number of peripheral resources to meet the four axis aircraft design requirements. Low cost inertial navigation system come true rely on the rapid growth of MEMS technology. A practical implementation of a quadrotor helicopter based on STM32 is described in this article, applying MPU6050 and other inertial sensors. The hardware structures and software flow chart of flight control are both presented. And the test results were compared with the numerical method of precise attitudesolution, achieve good effect. And the disadvantages of testing, including hardware and software problems at the same time modified update, gives the hardware improvement results.Use modified PID algorithm to control quadrotor attitude and Matlab to simulation and matching parameter of PID.At last,we finished the design of a quadrotor helicopter and make a objective assessment of it. |
