The document describes how to design high-speed digital control systems using the Analog Devices ADSP-2100 Family of Digital Signal Processors. It highlights the advantages of digital over analog implementations, such as increased noise immunity and parameter flexibility.
The note provides a comprehensive overview of hardware implementation, including interfacing with A/D and D/A converters for actuator control. It also covers software design methods, explaining how to organize modular code for executing complex algorithms like state estimators and PID controllers.
Typical applications include servo motor control, process control, robot arm control, disk drive head control, flight control, and general servomechanisms.
Digital controllers allow complex algorithms to be implemented in software rather than special hardware, enable parameter changes without affecting hardware, offer increased noise immunity and eliminate parameter drift.
Features include single-cycle instruction execution, three parallel arithmetic function units, single-cycle multiplications, efficient modulo addressing, and low power consumption.
