Title: Improvements in remote power control servo systems
Inventor: KELSALL RICHARD HOPE
IPC: G05D3/12
Filed: 1962-09-05
Abstract: 1,036,613. Control of A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 30, 1963 [Sept. 5, 1962], No. 34044/62. Heading H2J. [Also in Division G1] In a servo system, the orientation of structure 1 remains in step with pointer 3, the structure being driven. by three-phase induction motor 5. The pointer 3 and structure 1 are respectively coupled to the rotors of synchro units 13, 17, each having a single-phase rotor and a three-phase stator. A reference signal generator 21 energizes unit 13 and supplies rectifier 27, the stators of the synchro units being interconnected and the rotor of the unit 17 also being connected to the rectifier 27. The output of the rectifier indicates the sense and magnitude of the error in orientation of the structure and is connected to unit 33 which receives a signal at terminal 34 representing the desired slip frequency of the motor. The sign of the signal on line 35 depends upon that on lines 32, the magnitude being determined by the voltage at terminal 34. A tachometer generator 36 indicates motor speed and is connected to variable frequency generator 38 which also receives a signal from lead 35. The phase sequence of the output of the generator is determined by the sign of the signal on line 35, and the output frequency depends upon the sum of the voltages on lines 35, 37. Unit 41 multiplies the voltages on lines 39, 32 and supplies copying unit 45 for energizing the motor, resistors 49 providing negative current feedback. Displacement of pointer 3 causes a signal to appear on leads 32 whereby the motor is driven in the correct direction to remove the positional error. Where the motor is stationary, the unit 38 produces a maximum slip frequency, the magnitude of the voltage on leads 43 being determined by that on leads 32. As the motor accelerates, the tachometer generator produces an increasing voltage whereby the output frequency of the generator 38 rises, the slip frequency of the motor being maintained at the optimum value for maximum torque. As the structure 1 approaches its correct orientation, the error voltage on leads 32 decreases to decrease the stator voltage. The motor produces a braking torque when overhauled, and a reverse torque if it overshoots the desired position. The multiplier 41 may be of the Hall plate type.

In a modification, the inductance in circuit is in two parts, the interrupter being connected between these parts, and the load connected acorss the interrupter. A motor for driving the interrupter comprises a field in series with the interrupter and a Z-shaped soft iron rotor. With this arrangement the field winding forms one of the inductances. In a frequency changing arrangement a synchronous motor drives a subdivided interrupter.
