This paper presents a wind-driven DC power generation and control system modified by a doubly fed induction generator (DFIG), which stator is connected with a full-power diode rectifier to supply DC power to a stand-alone load and rotor is connected to the DC link with a PWM converter in charge of regulation of frequency and voltage on stator side. The transient character and behavior of current,...
The chattering is inevitable in using Variable Structure Controller (VSC) to control two-wheeled unstable vehicle. Although the traditional methods which are improved the reaching law and the switching surface effectively impair the chattering, they impair the anti-interfering of VSC at same time. To solve this problem, the dynamic pseudo sliding mode control with disturbance compensation term is...
Recent trends for A/D converters are here presented. New applications and technology scaling are the main driving forces on next generation ADCs. Adaptive ADCs and ultra-low power ADCs are motivated by new demanding specifications. Technology scaling stimulates the time-domain versus voltage-domain ADCs. Furthermore, various techniques to eliminate the power hungry opamps are in progress.
