An adaptive algorithm based on the dual Youla-Kucera parametrization is introduced enabling simple closed-loop identification and adaptation of a class of symmetric MIMO systems. The methodology exploits the algebraic approach to control system design. Necessary conditions for usage of the developed method are discussed and results are presented for the case of coupled drives control. Copyright...

A bstract We present a loop-by-loop method for computing the differential equations of Feynman integrals using recently developed dual form formalism. give explicit prescriptions fibration multi-loop forms. Then, we test our formalism on simple, but non-trivial, example: two-loop three-mass elliptic sunrise family integrals. obtain an ? -form equation within correct function space in sequence r...

with increasing the presence of microgrids (mgs) in the power systems, investigating the mg stability during transient faults is necessary. this study investigates the transient stability analysis of a mg supplied by multiple inverter interfaced distributed generations (iidgs) during fault. the transient stability of a mg is highly depends on the iidgs control strategy. a mg, simulated on matla...

This paper presents a novel buck converter with dual-loop control technology, which does not need to detect the inductor current directly. The structure of loops is easy implement, one loop controls output voltage, and other switching frequency. With dual mechanism, voltage frequency can be accurately controlled only by measuring input without sensing current. generate an 1.0–2.5 V when load ar...

The LCL grid-connected inverter has the ability to attenuate the high-frequency current harmonics. However, the inherent resonance of the LCL filter affects the system stability significantly. To damp the resonance effect, the dual-loop current control can be used to stabilize the system. The grid current plus capacitor current feedback system is widely used for its better transient response an...

This paper describes a dual-loop delay-locked loop (DLL) which overcomes the problem of a limited delay range by using multiple voltage-controlled delay lines (VCDLs). A reference loop generates quadrature clocks, which are then delayed with controllable amounts by four VCDLs and multiplexed to generate the output clock in a main loop. This architecture enables the DLL to emulate the infinite-l...

Though there are many strategies to control single-phase uninterruptible power supply (UPS) inverters, they suffer from some drawbacks, the main being complexity. This paper proposes a simple dual-loop controller for the single-phase UPS inverter with the LC filter. The suggested control scheme uses the capacitor current as the feedback signal in the inner current loop. No fictitious phase gene...
