Abstract

The electrical control system compares first data from a measurement with second data emanating from a setting controlled by the user. The comparison of data produces a voltage W1 which, via a circuit, controls the position of a movable element. The position of the moving element is regulated by a feedback circuit (7). A voltage value equal to W1 permits, firstly, the 'all or nothing' control of at least an electrical element. Secondly production, via a circuit (13), of a voltage V which is a function of W1. The voltage V determines, via a control circuit (5), the speed of an electric motor (6). The movable element, whose position is regulated by the feedback loop (7) and whose signals are a function of W1, generates a voltage W2. This voltage W2 is equal to W1 when the regulation of the movable element has been completed.
