Title: Electric motor control system
IPC: G05B13/00
Filed: 1967-12-07
Abstract: 1,203,807. Automatic control of speed. INTERNATIONAL BUSINESS MACHINES CORP. Dec. 7, 1967 [Dec.30, 1966], No.55705/67. Heading G3R. [Also in Divisions G4 and H2] A load is driven to a target position by an electric (e. g. stepping) motor through a deceleration zone which is bounded by the optimal deceleration trajectory 222 and a predetermined "corrective speed level" 233, which intersects 222 at 223, logic means operating to decelerate the motor when its speed is above the level 233 and to accelerate it when it is below. The system is such that the stop command is normally given 40 steps before the target position; if the motor has reached full speed 220 it will automatically decelerate along trajectory 222, but if it was still accelerating, 230, it at first decelerates along 232. If this continued the load would stop short, so when predetermined speed 233 is reached the motor is alternatively accelerated and decelerated so that the average speed is constant until the main trajectory is reached at 223 and this is followed to the target position 229. There are preferably three predetermined speed levels 233, 235, 236 at which the control can operate. In the complete system Fig. 1 a desired motion is set up in digital form by a processor 1 in a clockwise 3 or counterclockwise binary counter 7, the opposite one of which receives pulses from the motor corresponding to distance travelled by the load. The difference between the counters is detected by a comparator 5 which energizes lines 36 or 37 to instigate motion in the appropiate direction, and also one of these lines 31...34 according to the magnitude of the difference. These lines are connected to AND gates in a logic deceleration control system 10, the other inputs to the gates being on lines 26... 29 according to the motor speed, as determined by another logic circuit 9 in which pulses from the motor are passed through timing circuits. The output of 10 on line 45 is a stop command when the motor is required to decelerate. For high speed motion the controller 16 energizes the motor at two step intervals, but as the load nears the target position the circuit 10, over output line 45, causes single step control. This is also used in the event of an overshoot. The motor and its controller are described in Specification 1,105, 598 (Division H2A).
