Fundamentals of Self-Tuning Control 31/03/2008
Although proportional-integral-derivative controllers or ‘PID loops’ have been the de facto standard of industrial feedback control for more than 65 years, they’re not always easy to use. For PID loops to perform up to their potential, they must first be tuned to fit each application, then periodically re-tuned to maintain the desired closed-loop behaviour. Full Story...

Integrated motor/drive for single axis motion 01/11/2007
The SIEIDrive KFM 05 is a compact integrated ac inverter and motor, aimed at medium precision motion and speed control applications where full servomotor based systems would be unnecessarily expensive. Full Story...
