摘　　要：针对能源需求不断提高、太阳能热发电日趋成熟的现状,设计了一种基于DSP TMS320F2812的线性菲涅尔单轴跟踪系统。给出了系统硬件的详细设计过程,提出了跟踪系统的控制算法,完成了对整个系统的控制,使线性菲涅尔镜场中反射镜能实时跟踪太阳,并将太阳光线反射到固定安装的吸收器上。经联机上电试验,验证了该跟踪控制系统设计方案的可行性,达到了设计的跟踪精度。Aiming at the situation of energy demands continuing to improve and solar thermal power generation becoming mature,the linear Fresnel single-axis tracking system based on DSP TMS320F2812 has been designed. The design procedures of system hardware are given in detail,and the control algorithm for the tracking system is proposed. The control of overall system is completed and the reflector in linear Fresnel lens field can track the sun in real time,the sun rays are reflected on the absorber which is fixed mounted. The power-on online test verifies the feasibility of the design scheme of tracking control system,and the tracking accuracy of the design is achieved.
