Abstract
A mechanism for regulating an engine by using an actuator that is controlled in bang-bang mode, in which non-linearities are introduced in the control strategy in order to avoid putting excessive demand on an electric motor. The actuator is controlled by power supply pulses, which is a specific type of bang-bang control and, therefore, the actuator can receive a certain number of discrete commands. In one example, the actuator can receive two types of commands, for rotating in one direction and for rotating in the other direction.
