A comparative study of single-phase PWM converters having active filtering functions both on ac-input and dc-output sides have been carried out. Based on the function of the dc-output side active filter, two types of configurations, the RPM (ripple power managing) type and the APM (average power managing) type are compared to show their contrastive characteristics. The prototype system using DSP based control algorithms, i.e. deadbeet current control and voltage sensor-less technique using full-order observer, show the availability of the proposed system.

This paper presents a precision position control of induction motor using disturbance observer to reduce disturbance effects. It shows that proposed algorithm is strong in induction motor precision control for disturbance change. This system with disturbance observer using deadbeat control, which has high benefit, is good for quick disturbance compensation. To show this effectiveness the whole process is simulated by simulink, and also experimented by DSP6416 with TCP-IP network board.
