The author considers how considerable time and cost savings can be achieved by applying CAD/CAM techniques to many electrical wiring design, analysis and manufacturing applications. Because of certain difficulties, many CAD/CAM users have restricted themselves to simple 2D draughting, which is much more straightforward but of relatively little benefit. This is a great pity because the general-purp... View full abstract»

• ### Software engineering in an electronic engineering degree course

Publication Year: 1995, Page(s):45 - 48
| | PDF (378 KB)

Software engineering practitioners must tackle their problems in the same way as those in other disciplines if they do not wish to end up in a situation in which nobody trusts the software produced. The author discusses the developments in computer science degrees and then considers software engineering in an electronic engineering degree course biased to microprocessors.<> View full abstract»

• ### Failsafe systems gain the flexibility of the PLC approach

Publication Year: 1995, Page(s):43 - 44
Cited by:  Papers (4)
| | PDF (179 KB)

Failsafe systems, which control potentially hazardous operations to ensure they are shut down if faults occur, have in the past traditionally been hard-wired installations. But there are serious drawbacks to the hard-wiring approach-an inherent inflexibility, and lack of data communications facilities, to name but two. These are prompting a growing move towards using specialised systems based on p... View full abstract»

• ### Working together: a management summary of CSCW

Publication Year: 1995, Page(s):37 - 42

| | PDF (522 KB)

Computer front-end support is directed primarily at aiding the work of the individual, or adding together the results of work done by individuals-so much so that small computers (PCs) are frequently referred to as 'personal productivity tools'. This article summarises key issues in applying information technology to support collaborative work.<> View full abstract»

• ### Nonlinear control of a 175 kW gas burner

Publication Year: 1995, Page(s):29 - 34
Cited by:  Papers (2)
| | PDF (402 KB)

Sliding-mode control systems offer an effective and mathematically exciting approach to the robust control of uncertain, often nonlinear, dynamical systems which are subject to external disturbances. This article outlines the fundamental properties of the design philosophy. The development of a tracking control scheme for a multivariable thermal problem including the results of plant trials is the... View full abstract»

• ### Control configuration design for the aircraft gas turbine engine

Publication Year: 1995, Page(s):22 - 28
Cited by:  Papers (1)  |  Patents (2)
| | PDF (524 KB)

UK research into the design of multivariable controllers for gas turbines has been under way for several years. The results of simulation and engine test evaluations have been reported by Sutton (1991), and Shutler and Betteridge (1994). This article focuses on one aspect of multivariable controller design which is that of selecting outputs for closed-loop feedback control; this process is often r... View full abstract»

• ### Model-based control of a partial burn fluid catalytic cracking unit

| | PDF (311 KB)

A dynamic matrix controller (DMC) has been successfully installed on the fluid catalytic cracking reactor/regenerator section at RVI's Vohburg Refinery in Germany. A very short payback time was achieved based on increased feed processing and more stable regenerator operations (reduced catalyst addition rates). The controller has 6 inputs (manipulated variables) and 13 outputs (controlled variables... View full abstract»

• ### VSTOL first flight on an H/sub infinity / control law

Publication Year: 1995, Page(s):11 - 16
Cited by:  Papers (2)
| | PDF (450 KB)

An H/sub infinity / control law has been successfully flight tested on the DRA Bedford Harrier. This and subsequent flight tests demonstrated the practicality and power of H/sub infinity / as a design tool for systems with multiple inputs and outputs. The technique has potential both to reduce design time, and to improve robustness and performance for such systems. This article discusses the devel... View full abstract»

• ### Making advanced control work

Publication Year: 1995, Page(s):5 - 10
| | PDF (503 KB)

The benefits which advanced control technology can bring are significant and varied. Benefits derive from greatly improved dynamic performance of aerospace systems or substantially improved profitability for process systems. An advanced controller on a catalytic cracking unit is quite capable of yielding extra profits of between $5 and$10 million per annum, for example. The fundamental principle ... View full abstract»
