Abstract
Disclosed is a device for controlling the operation of a machine comprising at least one measurement sensor, one circuit to control this operation as a function of a signal sent out by the sensor and one input for the supply of alternating electrical power to the machine. This control device includes a memory known as a program memory containing a set of membership functions, a set of decision rules and a fuzzy logic program, a fuzzy logic processor used to prepare a decision signal that depends on the signal sent out by the sensor, on these membership functions and on these rules all at the same time and that is used to activate the operation of this machine with this decision signal, and in the program memory, additional membership functions that take account, as variables, of the signals available at the electrical supply input and of the rules that take account of these membership functions. The disclosure can be applied to devices for the control of electrical machines.
