This paper presents a new approach for single-phase shunt active power filter with LCL output filter based on the two-loop control theory. In this method unlike the conventional two loop control, internal loop stability theorem with considering delay effect is studied. Moreover, an observer based on the Kalman-filter is combined with the proposed control scheme, to reducing the numbers of power...
According to the characteristics like rapidity, time variability and the uncertainty of the input mechanical torque of front-end speed control wind turbine (FSCWT) with directly grid-connected and electrically excited synchronous generator (EESG), a double-loop H∞ control approach was proposed. In which, a simpilified structure of brushless excitation system was used. For the inner loop, first ...
Abstract In this paper, the dual closed-loop control strategy with fractional-order PI is applied to field of DC-DC converter, which effectively improves dynamic performance and static output voltage power electronic DC chopper converter. The open-loop transfer function Boost converter obtained by modeling analyzing operating principle small-signal model parameters double are combining frequenc...
high-precision three-axis attitude control scheme is vitally important to deal with the overactuated spacecraft, as long as the overall performance through rapid response can be in general acquired. due to the fact that the rigid-flexible spacecraft is somehow applicable, in so many academic and real environments, there is a consensus among experts of this field that the new insights in develop...
A robust cascade strategy combining an outer position predictive control loop and an inner H∞ pressure control loop is proposed and tested on an electropneumatic testbed for parallel robotic applications. Two types of cylinders are tested, the standard double acting cylinder and the rodless one. A position/pressure difference (or force) strategy is developed and implemented. As the behavior of ...

the problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. the former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. nevertheless, now we can obtain the location of eigenvalues ...
A control system combining input shaping and feedback is applied to a double-pendulum bridge crane subjected to external disturbances. The external disturbances represent naturally occurring forces, such as gusting winds. The proposed control method achieves fast point-to-point response similar to open-loop input-shaping control. It also minimizes transient deflections and disturbance-induced r...
