High-performance electric motors and their associated controllers are widely used in motion control applications. Feedback devices are employed to measure position and estimate motor velocity. The control system closes position and velocity loops using these feedback devices. A number of control schemes have been employed in industrial applications including closing a velocity loop within a pos...

Discusses the relation between cybernetics and architecture and pays tribute to Gordon Pask’s role and influence. Indicates Pask’s contribution to an increasingly environmentally responsive architectural theory that may lead to a more humane and ecologically conscious environment.

Importantly, I …nd that ho...
