The control unit for the goniometer has been developed and manufactured. The unit includes four independent programmable stepper motor control channels, three logical channels for analyzing the state of limit switches and a power supply. Powerful field-effect transistors of the company International Rectifier are used as controlled power switches. To generate output signals and communicate with a computer, an ATmega328 microprocessor is used in each control channel. This channel design allows you to control almost any type of stepper motors, you only need to replace the control program. The software is written using the WinAVR package which has a General Public License. Data transfer between the computer and the unit is carried out via the USB interface.

<img src="blob:http://ijra.iaescore.com/f3842e5c-715f-4e1e-9ffd-952309f5ccb1" alt="" />Stepper motors are broadly utilized in actual systems, which are marked by non-linear parameters such as internal, external noises and uncertainties from wireless network. As well, a suitable controller is required when the problem is to track the target signal. In this paper, robust controller based on model reference are investigated to wireless control and optimize position and time in stepper motors. The core impression to build a robust controller is to use a model reference control system. Furthermore, simulations are implemented to control stepper motor position and time in two cases: first, when the wireless network without any delay and packet dropout. Second, uncertain equations when the wireless network with time delays and packet dropout. Simulation results demonstrate that proposed controller has achieved and enhanced the performance in tracking and robustness.

Stepper Motor Control

This paper lays emphasis on thedevelopment of low cost controllers for stepper motors in contrast to its resource limitations such as memory size, few I/O pins and computing power compared to High-end designs. The microchip AVR ATtiny45 microcontroller was employed alongside a redesigned (reduced-input pin count) pulse distribution circuit for two H-Bridge drivers. The motor can rotate in both directions as well as possible speed control. The concept of the motor control signals was modeled in Matlab/Simulink, firmware was written in Atmel AVRStudio development environment, while theoverall design was carried out in Proteus software followed by Hardware implementation. Total material cost is about $5 which would be less in commercial production cases.

This paper describes the design and simulation of a distributed cooperative control algorithm based on multi-agents to synchronize a group of stepper motors. Modeling of the two-phase hybrid stepper motor in closed loop is derived in {d - q} rotary reference frame, based on field-oriented control techniques to provide torque control. The simulation obtained by MATLAB-Simulink shows that the distributed cooperative control effectiveness depends on the network topology defined by the graph.
