The use of a combustion engine to motivate a car has been questioned in recent times due
to the increasing concern of warming. As a result of this, the concept of driving
a car with an electric engine has become of particular interest. Dr. Geoff Walker and his
PhD students are working on the creation of the Universitys own electric car.
This thesis project is focused on deriving a control scheme to drive an induction machine
that could be applied to the electric car.
Process control is an application area of chemical engineering - an identifiable specialty for the ChE. It combines chemical process knowledge (how physics, chemistry, and biology work in operating equipment) and an understanding of dynamic systems, a topic important to many fields of engineering. Thus study of process control allows chemical engineers to span their own field, as well as form a useful acquaintance with allied fields. Practitioners of process control find their skills useful in design, operation, and troubleshooting - major categories of chemical engineering practice....
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.

Knowing that the plant parameters can vary within their lower and upper bounds, this
parametric uncertainty is formulated as an additive perturbation in the transfer function
matrix. It is important to note that the controller be designed with respect to worst case
uncertainty for each λij. This can be achieved by performing an optimization procedure
given by (61) for 200 frequencies. Here an element by element uncertainty bound model is
used for the characterization of upper bound of the uncertainty matrix. Then wij , which
satisfies (62) for each λij is given in matrix form as,...
The mcma framework, error control theory, error control system design, conclusion as the main contents of the document "Punctured Convolutional Coding Scheme for Multi-Carrier MultiAntenna Wireless Systems". Invite you to consult.
Networks, particularly large networks, are often divided into smaller subnetworks, or subnets. Subnets can improve network performance and control. A subnet address extends the network portion, and is created by borrowing bits from the original host portion and designating them as the subnet field,...
Control methods for high-performance ASDs with induction motors by direct selection of consecutive states of the inverter are presented in this chapter. The direct torque control (DTC) and Direct Self-Control (DSC) techniques are explained, and we describe an enhanced version of the DTC scheme, employing the space-vector pulse width modulation in the steady state of the drive.

With technology advancements in semiconductor devices such as insulated gate
bipolar transistors (IGBTs) and gate commutated thyristors (GCTs), modern highpower
medium voltage (MV) drives are increasingly used in petrochemical, mining,
steel and metals, transportation and other industries to conserve electric energy,
increase productivity and improve product quality.
Although research and development of the medium voltage (2.3 KV to 13.8 KV)
drive in the 1-MW to 100-MW range are continuously growing, books dedicated to
this technology seem unavailable.

This book presents and develops major numerical methods currently used for solving
problems arising in quantitative finance. Our presentation splits into two parts.
Part I is methodological, and offers a comprehensive toolkit on numerical methods
and algorithms. This includes Monte Carlo simulation, numerical schemes for
partial differential equations, stochastic optimization in discrete time, copula functions,
transform-based methods and quadrature techniques.
Part II is practical, and features a number of self-contained cases.
Robotics deals with the control of actuators using various types of sensors and control schemes. The availability of precise sensorimotor mappings – able to transform between various involved motor, joint, sensor, and physical spaces – is a crucial issue. These mappings are often highly nonlinear and sometimes hard to derive analytically. Consequently, there
