Abstract
This paper presents an industrial application of control systems for two-stage water supply of a city, based on a state space reaction, implemented on a variable speed electrical drives. A modeling and a simulation of the control system are presented. The lower level consumption compared with the control system based on a bipositional controller is proved.
