Systematic approach for PID controller design for pitch-regulated, variable-speed wind turbines

摘要

Variable-speed, horizontal axis wind turbines use blade-pitch control to meet specified objectives for three regions of operation. ^This paper focuses on controller design for the constant power production regime. ^A simple, rigid, nonlinear turbine model was used to systematically perform trade-off studies between two performance metrics. ^Minimization of both the deviation of the rotor speed from the desired speed and the motion of the actuator is desired. ^The robust nature of the PID controller is illustrated, and optimal operating conditions are determined. ^Because numerous simulation runs may be completed in a short time, the relationship of the two opposing metrics is easily visualized. ^(Author)
