Design, modelling and testing of mechatronic system controlled with system-on-chip device

Abstract

Mechatronic systems combine fine mechanics, electronics and information technology to achieve better performance with lower cost when compared with a mechanical-only device. Hydraulic systems, using hydraulic cylinders as actuators, are typical mechatronic systems. Efforts were made to develop a universal electronic module for controlling mechatronic devices and a test mechatronic system to validate this module was design and implemented. The paper presents design, simulation, implementation and testing of a mechatronic system controlled by a single chip electronic module based on 16 bit RISC microcontroller with large resources of memory and peripherals. The module was tested and special software was developed for a mechatronic application — an electro hydraulic position control system. The originality aspects of the work come from the unique design of electronic board able to handle a large range of mechatronic systems. The simple implementation of digital PID algorithm makes the module suitable for control of hydraulic applications like railway hydraulic damper test bench or hydraulic presses for recycling materials (chainsaw dust, PETs).
