Abstract

Objectives: The aim of the project is to develop an experimental laboratory test bench for comprehensive practical research of various types of selective-invariant electromechanical systems as a part of their engineering design. Method: The experimental laboratory test bench implements the Rapid Control Prototyping technology permitting the creation and testing of new control algorithms in a short time. This technology makes it possible to rapidly check theoretical results and develop innovative technical solutions prepared for practical implementation in real production equipment. Findings: The developed test bench is implemented by using a personal computer with Windows operating system and MATLAB software package with Simulink simulation environment and a real-time library. It contains complete controlledvelocity electric drive with information signal sensors and a mechanical oscillation source of load torque on the electric drive shaft. Computer and electric drive are coordinated by means of a NI PCIe-6343 input-output circuit board with PCI Express interface. The application of a test bench for experimental research of adaptive-invariant mechatronic systems under close to real operating conditions is shown. To a large extent the results of the test bench research of mechatronic systems confirmed earlier results obtained by simulation and computing experiment methods. Improvements: The experimental laboratory test bench enables rapid modification of control devices structure and parameters, intensity and spectrum of load torque oscillations, composition of the electric drive being tested.
