Abstract:
1. A system for optimizing the performance of a stepper motor by optimizing step-time sequence instructions given to the stepper motor, the system comprising: a host computer having a user interface for entering commands to the stepper motor and defining a desired operation profile used to create initial step time sequence instructions; and an interface computer connected between the host computer and the stepper motor having program means for executing a real-time controller program which receives real-time feedback from the stepper motor to obtain a measured operation profile for mathematically obtaining an objective function value indicative of a correspondence between the measured and the desired operation profile, and modifying the initial step time sequence instructions to produce optimized step time sequence instructions, so that the measured operation profile is modified to approach the desired operation profile, until the interface computer obtains a low objective function value indicative of an acceptable degree of correspondence between the measured and the desired operation profile, the interface computer transmitting the optimized step-time sequence instructions to the stepper motor.
