Embodiment Construction
[0022] Such as Figure 5 As shown, the smooth tracking control method applied to the trough solar concentrator according to the present invention, the specific implementation steps are as follows:
[0023] (1) Define the automatic tracking control method 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 If the angle difference △θ is equal to zero, the motor will stop;
[0024] (2) According to actual engineering needs such as stability and real-time performance, set the angle difference setting value △θ 0 And timing time t 0 ;
[0025] (3) Detect the start tracking signal of the solar thermal power generation system: when the tracking signal is valid, the tracking control of the target angle of the trough solar concentrator is performed, and step (4) is executed; when the tracking signal is invalid, the track...
