Abstract:Nowadays,servo control systems used in wind pendulum in China are mostly simple PID control and their core processors are mostly MCU.Considering the limitations of MCU in poor data handling capacity,slow data operation and insufficient flexibility,it is difficult to satisfy the function requirements and accurate control of wind pendulum.Therefore,a high-accuracy wind pendulum servo control system with the core of 32bit floating point DSP-TMSF2812@150MHz was designed,whose closed-loop control system was composed of gyroscope MPU6050,LED panel,manmachine interactive system and universal joint structure.Besides,the positioning of the gyroscope was adopted to provide the control system with the fan rolling speed data and pulse width debugging technique accurately controlled by neural network PID to control the large current driver chip BTN7971 so as to accurately control the revolving speed,direction as well as start-stop of the DC fan,thus a precise control to the position of the laser pen was realized.What’s more,it could realize the functions of rapid pendulum,line drawing and resting only under the dynamic control of DC fan.Meanwhile,it could also accurately draw a circle and quickly return to the state of circle drawing after being influenced by wind,so it had quite good robustness.The experimental result shows that this neural network wind pendulum control system has high control accuracy,good flexibility and timeliness.
