although lcl filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. recently, the single-loop control strategy has beensuggested for l or lc filter based grid-connected inverters. however, the use of single-loopcontrol directly in lcl filter-...

to enhance the closed loop performance in presence of disturbance, uncertainties and delay a double loop mixture of mpc and robust controller is proposed. this double loop controller ensures smooth tracking for a 3-axis gyro-stabilized platform which has delay intrinsically. this control idea is suggested to eliminate high frequency disturbances and minimize steady state error with minimum powe...

In this paper we introduce an equivariant extension of the ChernSimons form, associated to a path of connections on a bundle over a manifold M , to the free loop space LM , and show it determines an equivalence relation on the set of connections on a bundle. We use this to define a ring, loop differential K-theory of M , in much the same way that differential K-theory can be defined using the C...

We propose a correspondence between loop operators in a family of four dimensional N = 2 gauge theories on S4 – including Wilson, ’t Hooft and dyonic operators – and Liouville theory loop operators on a Riemann surface. This extends the beautiful relation between the partition function of these N = 2 gauge theories and Liouville correlators found by Alday, Gaiotto and Tachikawa. We show that th...
