This thesis addresses two neural network based control systems. The ﬁrst is a neural network based predictive controller. System identiﬁcation and controller design are discussed. The second is a direct neural network controller. Parameter choice and training methods are discussed. Both controllers are tested on two diﬀerent plants. Problems regarding implementations are discussed. First the neural network based predictive controller is introduced as an extension to the generalised predictive controller (GPC) to allow control of non-linear plant.
In this paper we present a new approach to controlling the behaviour of a natural language generation system by correlating internal decisions taken during free generation of a wide range of texts with the surface stylistic characteristics of the resulting outputs, and using the correlation to control the generator. This contrasts with the generate-andtest architecture adopted by most previous empirically-based generation approaches, offering a more efficient, generic and holistic method of generator control. ...
Today’s control system designers face an ever-increasing “need for speed” and accuracy in their system measurements and computations. New design approaches using microcontrollers and DSP are emerging, and designers must understand these new approaches, the tools available, and how best to apply them.
This practical text covers the latest techniques in microcontroller-based control system design, making use of the popular MSP430 microcontroller from Texas Instruments.

Computers now form an integral part of most real-time control systems.With the advent of the
microprocessors and microcontrollers in the last few decades the use of computers in control
applications has been ever growing. Microcontrollers are single-chip computers which can be
used to control real-time systems. Such controllers are also referred to as embedded real-time
computers. These devices are low-cost, single-chip and easy to program.

Despite the great technological advancement experienced in recent years,
Programmable Logic Controllers (PLC) are still used in many applications from the real
world and still play a central role in infrastructure of industrial automation. PLC operate in
the factory-floor level and are responsible typically for implementing logical control,
regulatory control strategies, such as PID and fuzzy-based algorithms, and safety logics.
Usually PLC are interconnected with the supervision level through communication
network, such as Ethernet networks, in order to work in an integrated form....

This subject focuses on management accounting for cost and control purposes in an organisational context. Emphasises the use of quantitative techniques and computer software including spreadsheets and presentation graphics.
inaccuracies lead to the deviation of operational space trajectory provided by the kinematic
One method to deal with this issue can be found in an adaptive control. Xu and Gu
proposed an adaptive control scheme for space robots in both joint space and operational
space [Xu et al., 1992, Gu & Xu, 1993]. However, the adaptive control proposed in [Xu et al.,
1992] requires perfect attitude control and the adaptive control in [Gu & Xu, 1993] is
developed based on an under-actuated system on the assumption that the acceleration of the
base-satellite is measurable.
The best-selling guide to the design of control systems for the fluid process industries is now updated and expanded. Emphasizing performance-based design and tuning, the new edition of the best-selling guide to process control provides engineers with reliable coverage of control technology principles for industrial fluid processes - from basic theory to advanced control applications.
This is a survey paper on Quality-of-Service(QoS) based routing. In this paper, we first introduce the
concept of Quality-of-Service and its background. Second, we discuss the concepts of QoS-based
routing, its objectives and main issues. After that, several types of QoS based routing algorithms are
compared, and the advantages and disadvantages of each type discussed. Then, the relations between
QoS based routing and some relevant techniques are studied, including traffic engineering, high level
admission control, resource reservation protocols(e.g.
A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes.
Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has
been extended to analog control as well.
A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system
is a cost effective solution for applications with a high ratio of digital to analog points in a system.
