<p>1509427 Control System WESTING- HOUSE ELECTRIC CORP 23 May 1975 [22 Oct 1974] 22846/75 Heading G3N A master and a slave motor 1, 2 are respectively connected to mechanisms 3, 4, e.g. in opposite screwdown ends of a workroll of a steel rolling mill Fig. 5, (not shown). The motors 1,2 are driven in synchronism. Position regulator 19 controls motor 1 in response to the difference between a reference 23 and the motor actual position measured by unit 15. This actual position is used as the reference for the slave motor by position regulator 20 which receives the slave motor actual position from unit 16. The outputs of the two regulators are received by summer 30 which controls slave motor 2.</p> |
