| Abstract: | In order to promote the energy conversion efficiency of solar energy panel, a solution of sun track control system based on MSP430 is proposed according to the principle of light intensity comparison. Light intensity signal acquisition circuit, the main controller using MSP430 and driving circuit of the stepper motor are introduced in the hardware design part. The modular design method is used, and the numerical filtration algorithm and control algorithm are adopted in the software design. Fast and accurate sun-tracking is realized by the way of motor operation control and signal processing of sensors. Results of experiment indicate that the system has excellent stability and flexible control characteristics and reaches the anticipated designing purpose. |
