Design of Control System of Two Degrees of Freedom of The Aerial Platform
Abstract: Two degree of freedom aerial platform is proposed in this paper. To existing microcontroller technology and control theory relying on, study how to from two aspects of hardware and software allows the system to can satisfy the aerial function. Using hardware core processor chip TSM320F2812. Pan tilt drive source DC motor, on top of the sensor selection chooses the encoder and gyroscope acceleration of PTZ for accurate analysis of position and gesture. The modular design concept, through the periphery of a motor driving circuit to drive the DC motor, the motor forward and inversion. Using PID algorithm to adjust the PWM output, to ensure that the head of the uniform, stable and accurate operation.
