Single Chip DSP Motor Control Systems Catching on in Home Appliances
(Reprinted from Appliance magazine, October 2000)
By David Krakauer, Strategic Marketing Manager for Embedded Control Systems, Analog Devices, Inc.
Introduction
Embedded DSP motor control is revolutionizing the appliance industry, not only by delivering the highest levels of motor performance, but also by the method employed to deliver that high performance. The computing power of a DSP allows users to exploit software modeling to implement closed-loop motor control creating a shift from hardware to software that yields significant advantages for motor and appliance manufacturers, ultimately changing their relationship. The latest generation of embedded DSP motor control ICs enables advanced control algorithms that, in turn, enable appliance manufacturers to reduce development times, costs and risks while, at the same time, enhance the efficiency, functionality, noise-reduction and performance of their products. While many processor options exist for electronic motor control, the DSP has long been acknowledged to be the best suited for motor control because of its strength in processing real world signals. Today, many appliance OEMs and motor manufacturers are rapid
ly adopting cost-effective DSPs as the motor control technology of choice.
Simple, Quick and Cost Effective
Appliance OEMs have discovered that today's generation of motor control DSPs are as easy to use and as inexpensive as conventional microcontrollers (MCUs), and
