Abstract
1289165 Control of motors ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI 18 Nov 1969 [19 Nov 1968] 56408/69 Heading H2J [Also in Division G4] A position control system for a moving element 40 comprises a switch having contacts 16, 27, 28 via which a constant speed control voltage supplied by a coarse position measurement device 46, 56 is fed to a motor 47 driving the element or a decreasing speed control voltage supplied by a fine position measurement device 50, 57, 30 is fed to the motor. A conductor 1 is fed with a step voltage equal to the difference between a voltage supplied by the device 46 and a voltage supplied by a generator 54 corresponding to the required position towards which the moving element is being moved. The device 46 is a reactor which cooperates with a Gray coded measurement rule 45 to supply signals to a decoder 56. The step voltage, each step of which represents one coarse measurement position of the element 40 is fed to the motor 47 via a peak clipping amplifier 2, an inverting peak clipping amplifier 3 and a conductor 9, as that when the element 40 is at least a few coarse positions away from its required stopping position a constant voltage is supplied to the motor. On reaching a position corresponding to one coarse measurement position away from the required stopping position, a peak-clipping amplifier 4 provides an output to a relay coil 5 and the output of the amplifier 3 energizes a relay coil 6 thus closing contacts 10, 12 to energize a relay 14 which closes contacts 15, 17 but opens the contact 16. A condenser 18 enables the output voltage of the amplifier 3 to be stored on the input of an amplifier 19. A sinusoidal, decreasing control voltage supplied by the synchronous generator 50 is fed via a synchronous receiver 57, a discriminator 30, an amplifier 20, and the closed contact 15 to the input of the amplifier 19. If these two inputs to the amplifier 19 are the same, a relay coil 21 is de-energized and contacts 22 are closed thus causing a relay coil 23 to close the contact 28 and connect the sinusoidal control voltage to the motor via the conductor 9. A circuit including relay coils 7, 8, 31, 32, 38 snd contacts 24, 34-37, 39 ensures that the element 40 always moves towards its required stopping position. A control voltage generator 54 is connected to the conductor 1 and the receiver 57 and may comprise a set of ten position controllers the number of which corresponds to the number of significant figures characterizing the positions of the element 40. The control may be used in a glass cutter, in automatic warehouse cranes, in automatic parking or in a furnace charging machine.
