A Servo System of Tracking Automatically for Solar Cell Based on Fuzzy Controller

The paper presented the servo system structure and work principle of tracking automatically, the system was composed of the sunlight transmission unit, the fuzzy logic unit, the output drive control unit, the comparing and adjusting unit, and it analyzed design methods and implementation of the closed-loop fuzzy controller, so has improved the system dynamic performance; the system controlled solar cell panels with the use of industrial personal computer (IPC) to driving stepper motor, and tracked automatically sunlight, in order to increase the conversion efficiency of solar energy, and to reduce the cost of photovoltaic power generation, thus there is a further promotional and applied values.
