This paper presents a digital signal processor-based permanent magnet synchronous motor (PMSM)-driven satellite reaction wheel with DC-link voltage adjustable according to speed and photovoltaic voltage. After the PMSM-driven reaction wheel is established, an improved current-controlled pulse-width modulation scheme is designed to yield precise sinusoidal winding current command tracking, and a simple, robust, model-following control scheme is designed to yield good dynamic speed response. To provide an adjustable and well-regulated DC-link voltage, DC/DC boost and DC/DC buck-boost front-end converters are established and compared. The stable chopping-controlled dynamic braking mechanism is also established.
