A numerical scheme for constrained optimal control problems

Zahra Shabani; Haleh Tajadodi

Volume 2, Issue 3 , July 2019, , Pages 233-238

  In this paper, a numerical technique is proposed to solve optimal control problems (OPCs) of Volterra integral equations (VIEs). We apply the linear B-spline polynomials to solve OPCs by VIEs. The B-spline function divides the interval into sub-intervals and then built a different approximating polynomial ...  Read More

Adaptive Gain Scheduling Control of Doubly Fed Induction Generator Based Wind Turbines to Improve Fault Ride Through Performance

Ahmad Khajeh; Zahra Shabani

Volume 1, Issue 1 , June 2018, , Pages 61-70

  The Doubly-Fed Induction Generators (DFIG) based Wind Turbines (WT) are widely used in WTs connected to power systems. Traditionally the back-to-back converters are used in order to control the DFIG. In this paper, an Indirect Matrix Converter (IMC) is utilized. Compared with back-to-back converters, ...  Read More
