The main task was investigation and precision improve­ment for a positioning drive, installed in a test rig for testing and calibration of the geodetic instruments at Vilnius Gediminas Technical University, Institute of Geodesy. Replacement of a stepper motor and a microstepping controller design increased positioning accuracy to 0.1''. Vibrations and noise of the test rig were significantly decreased using an optimized control algorithm, where resonating step frequencies were bypassed. The time of scale rotation between measurements (every 30°) achieved less than 1.5 min. Methods of the further precision improvement were selected, and this research is in progress now.

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.

Abstract The article describes investigation of rolling ball stabilization problem on a biaxial platform. The aim of the control system proposed here is to stabilize ball moving on a plane in equilibrium point. The authors proposed a control algorithm based on cascade PID and they compared it with another control method. The article shows the results of the accuracy of ball stabilization and influence of applied filter on the signal waveform. The application used to detect the ball position measured by digital camera has been written using a cross platform .Net wrapper to the OpenCV image processing library - EmguCV. The authors used the bipolar stepper motor with dedicated electronic controller. The data between the computer and the designed controller are sent with use of the RS232 standard. The control stand is based on ATmega series microcontroller.

Loop Control System

A control system of double closed-loop for two-phase hybrid stepper motor which includes speed closed-loop and current closed-loop is established on the basis of fuzzy-PID control algorithm, space vector pulse width modulation (SVPWM) method, space vector conversion and mathematical modeling of stepper motor. In the control system, the stepper motor model is established according to the mathematic model; the current and speed of stepper motor are controlled in feedback by the adopting fuzzy-PID control algorithm; the space vector conversion is carried out in the current/voltage conversion section, and the space vector pulse width modulation method is used to produce pwm wave. The performance of the doubled closed-loop control system for stepper motor is analyzed by the powerful modeling and simulation function of MATLAB/Simulink. The simulation results show that the control system has favorable control performance and dynamics characteristics.
