Embodiment Construction
[0022] like Figure 5 As shown, the steady tracking control method applied to the trough solar concentrator described in the present invention, the specific implementation steps are as follows:
[0023] (1) Define the automatic tracking control mode of the trough solar concentrator: if the difference △θ between the target angle θ and the actual angle θ' is greater than zero, the motor will rotate forward; if the angle difference △θ is less than zero, the motor will reverse turn; if the angle difference △θ is equal to zero, the motor stops;
[0024] (2) According to actual engineering needs such as stability and real-time performance, set the set value △θ of the angle difference 0 and timing time t 0 ;
[0025] (3) Detect the starting tracking signal of the solar thermal power generation system: when the tracking signal is effective, then carry out the tracking control of the target angle of the trough solar concentrator, and perform step (4); when the tracking signal is inv...
