Super-Twisting Sliding Mode Control Design for Cascaded Control System of PMSG Wind Turbine
Dinh Hieu Phan,ShouDao Huang 전력전자학회 2015 JOURNAL OF POWER ELECTRONICS Vol.15 No.5
This study focuses on an advanced second-order sliding mode control strategy for a variable speed wind turbine based on a permanent magnet synchronous generator to maximize wind power extraction while simultaneously reducing the mechanical stress effect. The control design based on a modified version of the super-twisting algorithm with variable gains can be applied to the cascaded system scheme comprising the current control loop and speed control loop. The proposed control inheriting the well-known robustness of the sliding technique successfully deals with the problems of essential nonlinearity of wind turbine systems, the effects of disturbance regarding variation on the parameters, and the random nature of wind speed. In addition, the advantages of the adaptive gains and the smoothness of the control action strongly reduce the chatter signals of wind turbine systems. Finally, with comparison with the traditional super-twisting algorithm, the performance of the system is verified through simulation results under wind speed turbulence and parameter variations.

Adaptive Position/Force Control for Robot Manipulators Using Force and Velocity Observer
Dao Minh Tuan,Phan Dinh Hieu 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.6
This paper presents an adaptive position/force control strategy and a velocity/force observer for three DOF robot manipulators APFC-VFO (Adaptive Position/Force Control-Velocity/Force Observer). The proposed control strategy based on the Slotine–Li adaptive control algorithm is designed to control the position and force of the end—efector robot interacting with the working environment. Moreover, the NGPI (New Generalized Proportional Integral) observer is established to estimate the velocity and force of robot manipulators. The advantages of the NGPI observer strongly reduce the oscillations of velocity and force under the efect of measurements noises. The observer convergence and control stability of the robot manipulator is proved in this paper. Finally, the simulation results are performed by Matlab Simulink software to validate the proposed control and observer.
