Slip motor speed control system based on LPC2136 and low cost CMOS camera

In this paper, designed the slip motor speed control system for packing rubber strip which is used in plastic steel door and window. The system, 32-bit embedded microprocessor LPC2136 as the control core, PWM speed control, velocity feedback from tachogenerator, rubber strip position feedback from the CMOS camera, has proved that CMOS camera´s image quality meets the engineering requirement; Slip motor speed is in the precision of 1 percent in scope of 0 to 1400rpm. Practical application shows that the system is reliable, stable and higher precision of control. The system design provides reference for similar control system and builds the basis for the design of intelligent control system.
