Communication between CAN Bus Control Devices and Virtual Machines
Richard Gagne,Vincent Remillard,Luca Berto,Lionel Pierreton 유공압건설기계학회 2017 유공압건설기계학회 학술대회논문집 Vol.2017 No.5
The fluid power industry has seen significant changes in the last decade, following the electrification of hydraulic technologies. By adding intelligence to hydraulic and pneumatic manufacturers’ components, designing and testing new fluid power applications require the additional expertise of control specialists. Since fluid power and control specialists use different CAE tools to create and virtually test their respective design, there is a need to create an integrated test environment to better communicate, understand and specify requirements of electro-hydraulic systems. In this paper, we will demonstrate how virtual components up to a complete machine developed on simulation software can be controlled by physical control devices (joystick, controllers…) using CAN bus communication. Examples of this will be illustrated for virtual systems built according to manufacturers’ specifications in Automation Studio™ and communicating with the physical controllers: a hydraulic simulation model (ex.: Eaton CMA valves) communicating with a programmable controller and multiple devices as well as Eaton HFX Controller, Danfoss PLUS+1<SUP>®</SUP> microcontroller or HydraForce CoreTek controller.

Mechatronic Challenges to Develop and Implement New Hydraulic Technologies
Richard Gagne,Vincent Remillard,Veronique Bader,Luca Berto 유공압건설기계학회 2016 유공압건설기계학회 학술대회논문집 Vol.2016 No.6
A new generation of hydraulic components with their integrated control capability, provides more precision and flexibility, but brings implementation challenges. To cope with this changing reality, the fluid power industry needs to redefine work processes surrounding mechatronic machine development, including the creation of training programs. Although a new generation of students accustomed with numerical simulation technologies is starting to emerge, their applied knowledge is often very limited. In addition, experienced specialists who possess this expertise are also getting scarce and harder to replace. To facilitate this technological transition, simulation and numerical analysis tools seem promising. However, to truly be effective, these tools must enable a collaborative work environment that will leverage the machine knowledge of everyone involved in the development process. The goal of this paper is to provide hydraulic engineers with an optimized and integrated approach, in-line with the working process evolution. This approach is demonstrated by two case studies of electrohydraulic independent-metering valves systems. The first one is the development of a hydraulic and control simulation environment of a CMA Eaton valve. The second one studies the interactions of a virtual Sun Hydraulic valve system that regulates the actuator movement under different loads, co-simulated with a PLC.
