Position Control of Hybrid Stepper Motor Using PIC16F877A Microcontroller

Pratkisha N.Balai | Jimit A.Talati


Abstract: Motion control of hybrid stepper motor for video surveillance system (CCTV) is very important issue in today life. Hybrid stepper motor is widely used in precision position application because resolution of hybrid stepper motor is high. In open loop control, the speed response of HSM suffer from large overshoot, oscillatory response and settling time. Additionally the motor must respond to each excitation change. If the excitation change is made too quickly, the stepper motor may lose some steps and therefore it will be unable to move the rotor to new demanded position. There for, a permanent error can be introduced between the load position and the expected by the controller. Due to this limitation, the stepper motor cannot be used without feedback sensor and closed loop control system with high performance application where the exact position or rotor speed is required.
