Boost PFC converter based on feedforward harmonic decoupling control
Diance yu yibiaoThe high penetration trend of power electronic equipment in local distribution network has led to the concentration, decentralization and wide area of harmonic sources, and the traditional point-to-point harmonic suppression is no longer applicable ...

Passivity/Lyapunov based controller design for trajectory tracking of flexible joint manipulators [PDF]
A passivity and Lyapunov based approach for the control design for the trajectory tracking problem of flexible joint robots is presented. The basic structure of the proposed controller is the sum of a model-based feedforward and a model-independent ...

Digital Sliding Mode Servo Systems with Preview Feedforward Compensation
IEEJ Transactions on Electronics, Information and Systems, 2003 AbstractA new design method of digital preview sliding mode servo system is proposed. In this method, sliding mode regulator theory is applied to an augmented error system. The equivalent control which makes the states of the error system stay on the switching surface is employed. Then, the sliding mode controller is designed.
