This paper presents a predictive direct torque control (PDTC) system with discrete multiple vector voltage (DMVV) and fuzzy hysteresis for a three-phase induction motor. A fuzzy hysteresis controller is proposed to establish a DMVV for estimating both flux and torque errors, which are the membership functions of the fuzzy system. DMVV switching timing ensures that an appropriate voltage vector is...
This paper presents a 10-bit Successive Approximation Register (SAR) Analog to Digital Converter (ADC) with 60.9 dB SNDR at 50MS/s while with 41.3uW power consumption. Several techniques were used to decrease the power consumption. First, Segmented architecture was used to decrease the total number of capacitance. Aligned switching with skip (ASS) method was used during copy MSB bits from coarse to...
