title = "High performance of PMSM driver IC integrated sensorless and current sensing circuits",
abstract = "This work proposes high performance of permanent-magnet synchronous motor (PMSM) driver IC integrated with position sensorless scheme and current sensing circuits. The position sensorless scheme is adapted with digital sliding mode observer (SMO) method that has high robust characteristics of motor parameter variations. For current sensing circuits, 10-bit successive approximation (SAR) analog-to-digital converters (ADC) and various (1∼16) gain amplifiers are implemented in the fabricated IC. The proposed PMSM driver IC is fabricated with 0.18um BCD process. Compared with the commercial module, with the accurate SMO scheme, a speed error is reduced to 0.7% at 3000rpm and a system efficiency is increased to 1.9 % at 3000rpm, 5N·m. The high precision position estimating driver IC is achieved without any position/current sensors.",
