Abstract
Two algorithms for the digital control of position of a three phase SCR controlled DC motor are compared. The digital control is novel in that the sampling period is variable and depends on the firing angles of the SCR's. While the algorithms are not new, their use with a variable sampling period in this application is. Performance is assessed through both simulation on a digital computer of the controlled motor and an implementation on a microprocessor based bench model. Both algorithms give equivalent performance in terms of step response to position commands.
