Embodiment Construction
[0031] Features and exemplary embodiments of various aspects of the invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention.
[0032] At present, the pitch control system mainly adjusts the blade pitch angle through the pitch angle feedback regulator. Feedback regulation is also called closed-loop regulation, and the three elements of feedback regulation include measurement, comparison, and execution. Specifically, it includes measuring the actual value of the controlled variable, and then comparing it with the expected value, using this deviation to correct the response of the system and performing regulatory control.
[0033] Generally, pitch angle feedback regulators used in pitch control systems include PI regulators, PID regulators, and the like. PID regulator is widely used because of its high control precision, and its adjustment pa...
