MathML in Polynomial Toolbox for Matlab
- Trang 284-286
This paper reports on a useful application of MathML to web presentation and
export/import of polynomial matrices from/to the Polynomial Toolbox for
Matlab/spl trade/. Two Matlab functions are described that can be used both for
high quality visualization of polynomial matrices on web and for data exchange
between Polynomial Toolbox and other software packages that compute with
polynomial matrices...

Robust /spl mu/-design of a disk drive servo system
- Trang 57-62
In this paper we show the application of the SLICOT routines, for robust control
system analysis and design, in a disk drive servo control system design. An
uncertainty model of the system plant is first derived which contains eleven
uncertain parameters including four resonance frequencies, four damping
coefficients and three rigid body model parameters. The /spl mu/-synthesis and
analysis method...

Thiết kế bộ điều khiển lái xe điện đa mục tiêu Dịch bởi AI
- Trang 69-73
Sự hiện diện của tính linh hoạt trong hệ thống truyền động ô tô, kết hợp với các
yếu tố phi tuyến như độ chơi của bánh răng, dẫn đến việc xuất hiện một phản ứng
dao động không mong muốn khi có sự thay đổi đột ngột trong tín hiệu ga. Dao động
này thường có tần số thấp (khoảng 2 đến 5 kHz) và có thể đủ lớn để gây ra cảm
giác khó chịu cho người lái xe cũng như sự thất vọng chủ quan về khả năng điều
k...

LFT representation of a longitudinal perturbed aircraft model by flatness approach
- Trang 230-235
In this paper, an linear fractional transformations (LFT) model representing,
the dynamic of the gap between a nominal model and a perturbed model of a
longitudinal aircraft fighter along a trajectory is given. The proposed approach
is based on a simplified model used to determine a nominal trajectory and
corresponding input. This simplified nonlinear model is a flat nonlinear system.
As the measu...

Numerical software in SLICOT for low order controller design
- Trang 51-56
We describe the model and controller reduction software recently developed for
the control and systems library SLICOT. Based on the latest algorithmic
developments, a powerful collection of Fortran 77 subroutines has been
implemented to cover the relative error and frequency-weighted model reduction,
as well as special controller reduction approaches. The new model and controller
reduction routine...

Designing model predictive controllers with prioritised constraints and objectives
- Trang 33-38
This paper shows how a class of objective functions can be incorporated into a
prioritised, multiobjective optimisation problem, for which a solution can be
obtained by solving a sequence of single-objective, constrained, convex
programming problems. The objective functions considered in this paper typically
arise in model predictive control (MPC) of constrained, linear systems. The
framework pres...

Multiobjective design using various control techniques
- Trang 1-6
This paper discusses three different multiobjective control schemes:
multiobjective PID control, multiobjective critical control and multiobjective
eigenstructure assignment. The multiobjective PID control considers a set of
frequency-domain performance requirements, such as gain margin, phase margin,
crossover frequency and steady-state error. The multiobjective critical control
addresses the rob...

An optimisation algorithm for designing fixed-structure controllers using the QFT method
- Trang 157-162
We propose a simple optimisation algorithm for designing fixed-structure
controllers for highly-uncertain plants. The method can be used to automate the
loop-shaping step of the quantitative feedback theory (QFT) design procedure and
guarantees robust stability and performance to the feedback loop for all
parameters in the plant's uncertainty set. To avoid over-designing the system,
the algorithm ...

Neural motion and evolutionary decision in robotic competition applied for molecular machine system design
- Trang ix
Summary form only given. The author presents a new approach within advanced
graphics simulations for the problem of nano-assembly automation and its
application for nanomedicine. The problem under study concentrates its main
focus on the design of autonomous nanorobots for assembly manipulation and the
use of evolutionary competitive agents as a suitable way to warranty the
robustness of such prop...

Multiobjective design for an integrated flight control system: a combination with model reduction approach
- Trang 21-26
Modem aircraft include a variety of automatic control systems that aid the
flight in navigation, flight management, and augmenting the stability
characteristics of the airplane. Typical control systems development involves
multiple requirements or objectives. On the other hand, the increasing level of
complexity and sophistication of aircraft systems leads to a hierarchical
architecture that the o...
