abstract = {The virtual earth concept, well known to designers of active
electronic circuits with operational amplifier components, is shown
to have a novel bicausal bond graph interpretation. This leads to
simplified bond graph modelling of such circuits. Some simple
operational amplifier circuits, together with a more complex active
filter are used to illustrate the approach.
A complex electro-mechanical system shows that the method is useful
in creating a unified bond graph model of systems involving both
analogue electronic and mechanical systems.},

title = {Continuous-time system identification of a food
extruder: experiment design and data analysis},
crossref = {SYSID03},
pages = {629--634},
abstract = {The introduction of product quality self-regulation to food-cooking
extrusion is an important aspect of process control within food
manufacturing industries. In order to design an automatic control
system for product quality, a mathematical model of the food
extruder is required. As first-principles models are difficult to
obtain in this context, a food extruder is a good candidate for
applying system identification tools.
This paper presents the application of continuous time system
identification to such a food cooking extruder. More specifically,
the reported application features an automated identification
experiment apparatus designed using relay feedback control
mechanisms and instrumented through existing real time supervisory
system for the extruder. Experimental data from the food extruder
are obtained and analysed using our identification approach.},

A new nonlinear predictive control law for a class of multivariable
nonlinear systems is presented in this paper. It is shown that the
closed-loop dynamics under this nonlinear predictive controller
explicitly depend on design parameters (prediction time and control
order). The main features of this result are that an explicitly
analytical form of the optimal predictive controller is given, on-line
optimisation is not required, stability of the closed-loop system is
guaranteed, the whole design procedure is transparent to designers and
the resultant controller is easy to implement. By establishing the
relationship between the design parameters and time-domain transient,
it is shown that the design of an optimal generalised predictive
controller to achieve desired time-domain specifications for nonlinear
systems can be performed by looking up tables. The design procedure is
illustrated by designing an autopilot for a missile.},
