A bidirectional converter (BDC) is required in areas where generated energy is stored. Some of the application areas are uninterruptible power system, transportation,, flywheel energy storage systems, etc. Bidirectional flow of power using buck mode and boost mode along with efficiency and high power density is important need of such systems. This report proposes a new topology of BDC with the ...

A special case of multiple frame prediction is the dual frame buffer, where an encoder uses both an immediate past frame and a long term past frame for motion compensation. Using a dual frame buffer together with intra/inter mode switching improves the compression performance of the coder. In this work, we investigate the effect of feedback in making better mode-switching decisions in the conte...

We propose a stability analysis method for sampled-data switched linear systems with finite-level static quantizers. In the closed-loop system, information on the active mode of the plant is transmitted to the controller only at each sampling time. This limitation of switching information leads to a mode mismatch between the plant and the controller, and the system may become unstable. A mode m...

The prediction of switching dynamical systems requires an identiication of each individual dynamics and an early detection of mode changes. Here we present a uniied framework of a mixtures of experts architecture and a generalized hidden Markov model (HMM) with a state space dependent transition matrix. The specialization of the experts in the dynamical regimes and the adaptation of the switchi...

The proposed zero-current switching switched-capacitor (ZCS SC) DC-DC converter is an innovative bi-directional power flow control conversion scheme. A zero-current switching switched-capacitor stepup/step-down bi-directional converter is presented that can improve the current stress problem during bi-directional power flow control processing. It can provide a high voltage conversion ratio of n...

This paper focuses on the implementation and performance analysis of adaptive switching between STBC and SFBC OFDM systems [1].Here in this paper we proposed an adaptive transmission technique for MIMO OFDM systems using adaptive equalization algorithms (ZF,MMSE) where the channel response are unknown a priori and time variant. In this paper two selection criteria, correlation of the channel an...

In this paper, we develop a nonlinear observer for switching linear systems. The developed state observer offers the properties of being selftuning without any information about the switching instants and the current mode of the switching system to be observed. Numerical example is provided to highlight the usefulness of the developed results.

Variable structure control system design methods are applied to the problem of aircraft spin recovery. A variable structure control law typically has two phases of operation. The reaching mode phase uses a nonlinear relay control strategy to drive the system trajectory to a pre-defined switching surface within the motion state space. The sliding mode phase involves motion along the surface as t...
