Bond Graph Project},

pages = {123-128},
abstract = {The rapid growth of GNU/Linux in recent years has
focused attention on free and open source
software. MTT (Model Transformation Tools) is, as
far as the authors are aware, the only open source
project related to bond graphs. This paper surveys
MTT in its present form and invites collaboration
from the wider bond graph community.}

Integrated System Modelling},

abstract = {Bond graph modelling has been applied widely and
many ideas have been collected from the user
community for improvement, particularly associated
with federated systems. A project is underway to
address these via a prototype toolset with the
working title of Next-Generation Transformation
Tools (NTT). This paper will summarise the
motivations behind this development and describe
notational changes that have been found
necessary. This should provide useful insights into
the problem of large-scale bond graphs.}

title = {Continuous-time {LQ} Predictive Pole-placement Control},
crossref = {IFAC16},
abstract = {
The previously developed Predictive Pole Placement (PPP)
controller is modified to give enhanced numerical and
stability properties by embedding the method in a
linear-quadratic formulation to give a linear-quadratic
PPP (LQPPP) controller. Input, output and state
constraints are considered using an natural quadratic
programming (QP) formulation of LQPPP. Illustrative
examples are given.

title = {Continuous-time System Identification of Nonparametric Models
with Constraints},
crossref = {IFAC16},
abstract = {Although structural constraints such as model order
and time delay have been incorporated in the
continuous time system identification since its
origin, the constraints on the estimated model
parameters were rarely enforced. This paper proposes a
continuous time system identification approach with
constraints. It shows that by incorporating physical
parameter information known a priori as hard
constraints, the traditional parameter estimation
schemes are modified to minimize a quadratic cost
function with linear inequality constraints. Using the
structure of Frequency Sampling Filters as the
vehicle, the paper shows that the constraints can be
readily imposed on continuous time frequency response
estimation and step response estimation. In
particular, a priori knowledge in both time-domain and
frequency domain is utilized simultaneously as the
constraints for the optimal parameter solution. A
Monte-Carlo simulation study with 100 noise
realization is used to demonstrate the improvement of
the estimation results in terms of continuous time
frequency response and continuous time step response.}
