Original Abstract

Nowadays a Stewart platform six DOF parallel mechanism is constructed on FME BUT. The mechanism con-tains two plates linked to each other by six linear actuators. The mechanism control design task has several sub-tasks. One of which is the control design of a linear actuator (single mechanism link). The linear actuator proto-type consists of a DC motor with IRC sensor, ball screw and gearings. A model of the mechanism dynamics was built for the control purposes in state space form. The control is implemented in NI LabVIEW from where it is possible to control the constructed prototype through a real-time computer and a high-level amplifier. A laboratory device for DC motors control, designed in Laboratory of electrical devices UAI FME BUT, is used as a high-level amplifier of a hardware card output. NI LabVIEW environment also contains built-in tools for system simulation and identification which will be used for improvement of the model and control algorithms. The control algorithm will be tested on the experimental DC motor.
