Manufacturing Execution

Manufacturing Execution System (MES) links plan management and workshop control in an enterprise, which is an integrative management and control system of workshop production oriented to manufacturing process. To overcome the difficulties of traditional software development method, development of MES based on component is adopted to prompt development efficiency and performance of MES, which can be more reconstructing, reuse, expansion and integration, and MES domain analysis driven by ontology is investigated in detail. MES domain analysis driven by ontology is feasible and efficient through developing a pharmaceutics MES which applied in a pharmaceutics manufacturing factory.

Abstract This paper investigates an effectiveness of vehicle dynamic control (VDC) system based on torque vectoring technique using in-wheel-motors to improve the performance of articulated vehicle systems. A 10 degree-of-freedom (DOF) articulated vehicle model including a tractor and a single axle trailer has been developed and its responses are validated with commercial vehicle software of Trucksim. This model includes a nonlinear tire model (MF tire), a hydraulic damping at the hitch, and a traction system using in-wheel-motors at the trailer axle. In this paper, a yaw control system is developed to track the reference yaw rate with application of yaw moment at the trailer axle using torque distribution of in-wheel-motors. The effectiveness of the proposed control system is validated through simulation of sinusoidal steering maneuver on high mu and slippery road conditions. The simulation results show that in-wheel-motors can improve safety and performance of articulate vehicle systems.

Search Capability

An assessment is made of a surveillance-radar control system designed to provide a sector-search capability and continuous control of antenna speed without unwanted torque-reaction on the supporting mast. These objectives are attained by utilizing regenerative braking, and control is exercised through Perbury CVTs. A detailed analysis of the system is given. The models derived for the Perbury CVTs supplement the qualitative data contained in earlier papers. Some results from a computer simulation are presented. Although the paper is concerned with a particular problem, the analysis of the CVTs, and the concept of using energy transfer to control large inertial loads, are of more general interest.

Command And Control System

We proceed from the perspective of object-oriented analysis and design modeling, focusing on the model design of command and control automation system, using Colored Petri Net (CPN) to a command and control systems for dynamic design and simulation run. A method of mapping from UML product can be used for logical, behavioral and performance aspects of architecture evaluation methods of CPN executable models is proposed. We first descript the command and control system for UML modeling generally, and then elaborate the process from UML products are mapped to the CPN build executable model of the command and control system.

Dresser Waukesha’s 275GL engine series, released in 2009, included an Engine System Manager (ESM) to manage and control critical engine operations. These engines are typically used in mechanical drive applications for natural gas compression as well as power generation at 2500 to 3300 kWb (3400–4500 bhp). The 275GL is now being offered in a low NOx configuration designated the 275GL+, that features a NOx based Air/Fuel Ratio (AFR) control. Market analysis determined that an engine with lower NOx output emissions while maintaining peak performance is of high importance. Utilizing a traditional oxygen based AFR system has limitations when controlling emissions at extreme low NOx values. In order to meet these needs and maintain a consistent low NOx level, development of a control system that allows an engine to achieve these requirements was essential. A NOx sensor based control system was developed to control extremely low NOx values while accounting for engine wear, humidity and fuel changes. An oxygen based AFR system has limitations that make it difficult, if not impossible, to use this approach for extremely low NOx levels. Some of these limitations can be attributed to sensor signal masking due to exhaust gases and having to correlate O2 to NOx for the specific application. This new NOx sensing functionality enables robust control of specific NOx emissions at varying engine and environmental conditions, yielding a powerful addition to the ESM engine control system applied on the 275GL engine. The NOx control running with ESM allows for the engine to achieve 0.5 g/bhp-hr NOx levels while maintaining fuel efficiency, fuel tolerance, and turndown range. This paper discusses the key testing, results and performance of this development when implemented on the 275GL+ engine.

Design Challenges

This chapter deals with hexapod walking robot design and operation. The first section gives a wide overview of the state-of-the-art on hexapod walking robots by referring both to early design solutions and to most recent achievements. Section two identifies the main design challenges that influence the technical feasibility and performance of these systems. In section three, a design procedure is proposed. In particular, the proposed design procedure takes into account mechanical structure, leg configuration, actuating and drive mechanisms, payload, motion conditions, walking gait, and control system. A case of study is carefully described as referring to previous experiences at LARM.
