The proposed control scheme is based on gain-scheduled reinforcement learning recurrent ANFIS type 2 (GS-RL-RANFIST2) pitch angle controller to maintain the rotor speed at its rated value while smoothing the output power and the performance of the pitch angle system. The practical application of...
Furthermore, the performance of the TLBO tuned FONPID pitch angle controller is compared with the performance of TLBO tuned gain﹕cheduled PID (GSPID), fractional﹐rder PID (FOPID), and nonlinear PID (NPID) based pitch angle controllers....
On one hand, the reference can be the pitch angle, obtained directly from a pitch angle-wind speed curve, and, on the other, the rated rotor speed or the rated power [24]. Commercial wind turbines with CPC strategy implement a simple PI controller, with rotor speed variation from rated ...

This paper has proposed a gain-scheduled controller with stability proof and guaranteed cost for a turboshaft driving a variable pitch propeller. In order to overcome the complexity of the nonlinear model, a linear parameter varying (LPV... F Lashkarboluki,A Khosravi,J Sadati 被引量: 0发表: ...
Test the controller on the nonlinear plant in Simulink. Aircraft Model Consider a three-degree-of-freedom model of the pitch axis dynamics of an airframe. The states are the Earth coordinates (Xe,Ze), the body coordinates (u,w), the pitch angleθ, and the pitch rateq=˙θ. This figure...

Nonetheless, if you have a unique approach or a unique angle that will give you a competitive edge, show how that will play to your advantage. Say Ariel Poler, "That’s going to win you investors. But don’t pretend everyone else is an idiot and only you get it.” Don’t let per...
A method of controlling blade pitch angle, including comparing demanded and measured blade pitch angle and calculating any difference therebetween, in a primary electrical control s
Passive fault-tolerant control method for wind turbine based on linear parameter varying (LPV) variable gain making the input wind speed dynamical change along with the parameters of a controller by employing the LPV variable gain control method; and finally, perf... 吴定会,李意扬,沈艳霞,... 被...
