摘　　要：为在浮空器平台上实现对太阳的准确跟踪,分析目前太阳能光伏发电系统中常用的跟踪方法和浮空器上太阳跟踪装置的特点,阐述被动式太阳跟踪方法和差分进化算法的原理。由于浮空器平台的不稳定性,在ZieglerNichols(Z-N)法整定PID参数的基础上,运用差分进化算法对PID参数做进一步优化,可实现太阳能的充分利用,减少动态跟踪时驱动电机的能量损耗。仿真结果表明:该控制方法可改善系统的动态特性,使系统的鲁棒性更强,为工程应用提供可靠的理论依据。For the purpose of accurate solar tracking on the platform of aerostat, the common tracking method in current solar PV power system and the characteristics of solar tracking equipment on aerostat were analyzed ; the passive solar-tracking method and the theory of differential evolution algorithm were expounded. Because of the instability of aerostat, the PID parameter through differential evolution algorithm was optimized on the basis of Ziegler-Nichols method, realizing the full utilizationse of solar energy, and reducing the energy-loss of drive motor in the dynamic tracking process. The simulation results indicate that the control method can ameliorate the dynamic feature of tracking system, strengthen the robustness of the system, and provide reliable theoretical basis for engineering applications.
