Design of revs curve programmable servo control system

A revs curve programmable servo control system on servo motor has been developed in order to look for optimum control parameters of a single crystal growth. The main parts of the system are Micro Controller Unit (MCU), AC servomotor, Digital Analog Converter (DAC) and so on. By means of a new arithmetic, a crucible rotary speed realized linear change in a process of acceleration and deceleration for given revs in 1∼600 revolutions per minute (rpm). Its control precision is high, and the program method is simple.
