为了了解太阳跟踪器的具体性能,提高设计效率,采用ADAMS和Simulink软件对太阳跟踪器的工作过程进行了虚拟仿真分析。首先利用ADAMS软件建立了系统的动力学模型;利用Simulink软件建立了基于速度闭环的双轴控制系统。然后搭建了机-电联合仿真模型,并进行了仿真研究。分析了太阳跟踪器双轴控制系统的基本性能,确定了太阳跟踪器的目标输入曲线,完成了联合仿真计算。联合仿真结果表明:系统对太阳高度角输入曲线具有较好的跟踪能力,开始跟踪1.5s后系统跟踪非常稳定,跟踪误差小于目标幅值0.1%。得到的结果表明:所建的动力学模型和控制系统模型能够准确地描述跟踪器的工作过程,提高设计效率,可为实际物理样机的开发提供可靠依据。

To understand the performance of a solar tracker and to improve its design efficiency,the virtual simulation towards the working process of a solar tracker was accomplished by using software ADAMS and Simulink.First,the dynamics model of the solar tracker was constructed by using ADAMS.Then,the control system suitable for the double axis of solar tracker was established based on a speed closed loop by using Simulink.Thereafter,the co-simulation model was set up and the corresponding simulation was completed to determine the basic performance of control system.Finally,the target curve was input into the model,and the co-simulation was accomplished.The simulation results demonstrate that the system has excellent path tracking ability according to the sun elevation angle input curve.After 1.5stracking,the system becomes stable as well as the tracking error is less than 0.1%of the target value,which shows that the dynamics model and control system model are accurate and can provide a reliable basis for the development of actual physical prototypes.
