This study investigates a high friction fruit conveyor system based on a traditional frictionless ball-and-beam system (BBS). Both share commonalities of behavior i.e. controlling an object by manipulating the platform angle. The BBS system includes a rubberised strip to make increase its friction slightly. The inherently unstable BBS is stabilised with a simple PID controller to permit system identification...
Severe in-vehicle air quality may affect drivers and passengers' health and reduce customers' satisfaction or experience with the vehicles, especially in some areas with heavy pollutants. Nowadays, in-vehicle cabin air quality management draws more attention from automakers. The advances in climate control include improved filtering systems and advanced climate control management based on air quality...
In normal conversation, the meanings of data, information and knowledge can often be used interchangeably. At some level of approximation, these three terms are near enough the same. In the domain of computing and in particular the topic known as artificial intelligence, to accept this generalisation is to lose some resolution in a plausible model of the origin of thought. This paper offers an interpretation...
Data analytics services are on the rise, fostered byan increasing number of wearables and industrial sensors whichare connected over the Internet. As a result, users who want totake advantage of these services are confronted with the challengeof keeping their private data and business secrets secure, whilestill providing the information required for the analytics serviceto operate. Traditional access...
The cooperative flight of multiple UAVs is one of the hotspots of recent research. The design of simulation system for multi-UAV cooperative guidance is discussed to build a total factor simulation system. It is very important to analyze the algorithm of cooperative guidance and assess with it. Firstly, the component and function of simulation system for cooperative guidance are discussed, then the...
The sensing data is usually transmitted simultaneously from the sensor to the controller in conventional control systems. However, in networked control systems it is possible that a set of sensing data is transmitted via multiple separate data packets due to the multiple, geographically dispersed sensors. This scenario, referred to as “multi-packet transmission”, brings to the system different delays...
This work presents a model-based networked control structure with a feedback-based communication policy for spatially distributed processes modeled by highly-dissipative nonlinear PDEs with measurement sensors that transmit their data to the controller/actuators over a resource-constrained wireless sensor network. Initially, a finite-dimensional system that captures the slow dynamics of the PDE is...
In order to improve the precision and efficiency of teleoperation real-time task, a new method, dual-virtual model overlapping display teleoperation control system is proposed. The accurate and efficient control of remote robot can be realized by controlling the virtual operation model and virtual feedback model overlapping displayed in the same display window. For the control variables for virtual...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
