Control of production of mechatronic drives for various applications provides the most efficient use of materials and the required operating characteristics of devices. The paper proposes a control system for technological process of production of mechatronic drive based on tests of the magnetic properties of structural elements that provides the optimum use of all available resources of ferromagnetic...
In order to detect the nonlinear characteristics (flow hysteresis) of aviation fuel valves and to improve the accuracy and efficiency of fuel valve performance test, a computer aided fuel valve automatic test system is designed. The test system mainly consists of industrial control computer, data acquisition card, signal conditioning circuit and test software developed on the LabVIEW virtual instrument...
Several EDA tools automate the debug process1,2 or part of the debug process3,4. The result is less manual work and bugs are fixed faster5. However, the actual process of fixing the bugs and committing the fixes to the revision control system is still a manual process. In this paper we explore how to automate that last step: automate bug fixing. First we discuss how the automatic bug fix flow should...
This paper firstly presents the characteristics of the bus 1553B and its protocol implementation in the electronic equipment test system, and then introduces the implementation process for the bus controller and remote terminal in the system in detail. LabVIEW was adopted to realize the function in main controller and test terminal in the electronic equipment test system. The operation command, test...
In this paper the autopilot setup and the lessons learned from a successful balloon launched high altitude glider mission will be presented. Flying an unmanned aerial vehicle inside the stratosphere means operating it outside visual line of sight, in low pressures and cold temperatures. These environmental conditions pose many challenges to the UAV aerodynamic design, the autopilot system and the...
The ability to move independently in the space of environment predetermines many other possibilities for the invalid. Key to this are lower limb prostheses and, in particular, transfemoral. Provide lot of quality characteristics of transfemoral prostheses is possible already at the stage of synthesis. In this paper describes the design process of specialized mechatronic testbench for testing modules...
This article describes the design and implementation of visualization and communication system used to control a robotic head. This document also describes the solution for communication protocol used by internal data bus of the robotic equipment and the proposal for communication protocol used to communicate with the visualization system section. Verification method and testing of the proposed cyber...
A self-contained cartridge and an integrated instrument for the automated molecular testing are described. The proposed cylindrical cartridge consists of multiple chambers containing all necessary reagents such as specimens, lysis, wash, and elution buffers. The system provides a chain of automatic processes for the molecular test of sample preparation, amplification, and detection. Sample preparation...
Rehabilitation of disabled persons who have lost their lower limbs due to various reasons and the ensuring to them the opportunity an active lifestyle is an important social task. It can be solved by the widespread introduction in the rehabilitation practice a low-cost intelligent prostheses, the functionality of which depends not only on the design type, but also, not least, from the realized control...
This study aims to implement fuzzy logic controller using Mamdani and defuzzification method of Centroid, as a controller for train speed. Research methodology employed consists of Modeling, Design, Testing, and Analysis. At Modeling phase, the system is modeled utilizing transfer function model; at Design phase, the system with fuzzy logic controller is designed; at Testing phase, system output is...
Testing aims at detecting (regression) bugs in production code. However, testing code is just as likely to contain bugs as the code it tests. Buggy test cases can silently miss bugs in the production code or loudly ring false alarms when the production code is correct. We present the first empirical study of bugs in test code to characterize their prevalence and root cause categories. We mine the...
This paper presents a test framework for a large-scale message broker system for consumer devices, where communication is between devices and goes through a message broker. In testing such a system, administering tests is a burdensome task, because a tester has to design and operate a test application managing multiple connections and to validate complicated traffic patterns between clients via a...
The activity of turning on and off the electronic equipments and lights were often considered a nuisance and disturbing worked that often the equipment was on continuously without being shut off. This certainly can reduce the lifetime of the equipments, waste the electrical energy and cause an uncontrolled indoor climate condition. Therefore, it is necessary to design a control system to adress this...
At the Universidad Politécnica de Madrid students attending a course on concurrency are taught a high-level formalism which permits concise specification of shared resources. This formalism is used to express safety-critical access policies for typical control problems such as robot plants. Students are moreover provided with programming recipes for implementing such shared resource specifications...
The development of Satellite Assembly, Integration and Test Centre at Malaysia Space Centre is another step taken by Malaysia Space Agency (also known as ANGKASA) in developing the space sector in the country. The centre provides a facility for assembly and integration of satellite as well as the launch and environmental testing for local and others countries in South East Asia region. It comprises...
A mobile trolley allows engineers to do integration work at various parts of the satellite body, thus preventing mishandling of the satellite. Unfortunately, the existing height multi-purpose satellite trolley in Satellite Assembly, Integration and test facility of Malaysia Space Centre is not an adjustable type and there is no platform to work safely around the satellite. Existing conditions in the...
In this paper, reliability test device for a high speed pneumatic cylinder was developed, Loop operation control, leakage measurement, displacement-time measurement and other test items can be completed in this measurement and control platform. Pneumatic circuit structure, working principle and realization, hardware components and program design in measurement and control system, and the initial parameter...
Automotive embedded control systems are a vital aspect of modern automotive development, but the considerable complexity of these systems has made quality checking a challenging endeavor. Simulation-based checking approaches are attractive, as they often scale well with the complexity of the system design. This paper presents an overview of simulation-guided techniques that can be used to increase...
In Software defined networking (SDN), security mechanisms such as firewalls need to deal with dynamic network environments. This raises challenges for quality assurance of these security mechanisms. This paper presents a case study on model-based testing of SDN firewall programs. The subject program is the firewall module of Floodlight, one of the most popular SDN platforms in Java. We model the expected...
