Title:
HYBRID DIGITAL-ANALOG CONTROLLER
Document Type and Number:
WIPO Patent Application WO2001044681
Kind Code:
A9
Abstract:
A Hybrid Digital-Analog controller (10) configured to dynamically adjust the gains of the control parameters of an analog controller (20) to optimize the control parameters of a monitored controlled variable. The controller (10) receives a sampled signal representative of the controlled variable, and creates a digital control signal (40) based on the sampled signal. The analog controller (20) has a plurality of digitally variable resistors (45) which control the gains of the analog controller (20).
