Simulation and Implementation of Multiple Unipolar Stepper Motor Position Control in the Three Stepping Modes using Microcontroller

Abstract

<p>This paper presents a multiple unipolar stepper motor position control system using microcontroller (MCU) in anticlockwise and clockwise directions. The open loop controller of the implemented position control system for the three stepping modes of operation has been designed and developed with three stepper motors and without position feedback. The MCU is programmed using flowcode software package to generate the pulse signals with the desired stepping sequences and step angles. These pulse signals are necessary to drive the three stepper motors in the three drive modes (wave-step, full-step, and Half-step) according to the control algorithm. Three devices of 8 Channel Darlington Driver (chip ULN2803) are used to drive the three stepper motors and provide them with the sufficient current. The position control system has been simulated using proteus design suite software package and the controller has been implemented using low cost PIC16F877A (MCU). A reliable and accurate position control of the stepper motor is achieved by this position control system. </p>

“…Finalmente cuenta con una reducción 1/64 en la salida al eje motriz, por lo que en este eje se tiene una resolución de 2038 pasos por giro funcionando en paso completo. Se utiliza en el modo paso completo por brindarnos ligeramente mayor torque para mover la clapeta [5] y dado que mayor resolución del movimiento no brinda ningún beneficio para el control de la temperatura de la precámara. En la figura 6 se observa el motor paso a paso seleccionado.…”

Controlling the half-step mode operation of the variable reluctance stepper motor by using Mamdani type of fuzzy logic controller

“…Different researches about the stepper motor have been proposed. A microcontroller (MCU) is used to control the position of multiple unipolar stepper motors in both directions, clockwise and counter clockwise, as in [2]. Silaban et al [3] used the field programmable gate array (FPGA) to control the stepper motor in the both directions by making the motor move in the half and full step operations modes.…”

Stepper motor movement design based on FPGA

“…Xilinx Ise 14.5 in this research is used to create a program with VHDL (Very high speed integrated Hard Language Description Language) type and FPGA Isim is used to test and simulate the coded program that has been prepared [16][17][18][19][20]. The hardware description language(HDL) is used in FPGA to communicate with hardware which is very easily interfaced with them, Logic gates are used in FPGA as a memory blocks, these logic gates are interconnected with each other due to these feature it performs complex functions and compute fast response [21][22][23][24][25]. The trial is the first step in the process of producing the right motor movement and real time.…”
