Software Resolver-to-Digital Converter for Compensation of Amplitude Imbalances using D-Q Transformation
Resolvers are transducers that are used to sense the angular position of rotational machines. The analog resolver is necessary to use resolver to digital converter. Among the RDC software method, angle tracking observer (ATO) is the most popular method. In an actual resolverbased position sensing system, amplitude imbalance dominantly distorts the estimate position information of ATO. Minority ...
متن کاملFPGA Based Resolver to Digital Converter Using Delta-Sigma Technology
This contribution describes a new FPGA based method to convert the analog resolver signals to a digital position signal using Delta Sigma ADC technology. By using a 2 order ∆Σ modulator it is possible to increase the effective resolution. In a servo drive the significant better signal to noise ratio can be used to build a smoother motor current (less noisy), or to increase the tracking loop ban...
متن کاملCompensation of Analog-to-Digital Converter Nonlinearities using Dither
Analog-digital converters are inherently nonlinear. Conventional A/D conversion allows no real remedy afterwards. However, an alternative is to increase the available information by observing the transition instants, even with a conventional ADC. Performing the conversion with significant oversampling data points at threshold level crosses can be used. The values of these samples are precisely ...
متن کاملsignal specific successive approximation analog to digital converter
چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...
15 صفحه اولAn Adaptive Digital Compensation Design for Buck Converter Topology
This paper presents a digital type III compensator that needs no calculation made by a designer. First an analog type III compensator is designed for a buck converter and based on it the digital model is obtained. Both the analog and digital approaches are simulated in PSIM and the digital compensator is written in a Microchip dsPIC for experimental results. The dynamic response of these contro...
