Ch Control System Toolkit 2.5 Released
DAVIS, Calif., July 28, 2008 -
SoftIntegration, Inc., the leader of
scripting technology for ubiquitous computing,
today announced the release of
Ch Control System Toolkit
version 2.5.
Ch is a superset of C interpreter for scripting, 2D/3D plotting,
numerical computing, shell programming and embedded scripting.
Ch Control System Toolkit is designed for modeling, design, and analysis of continuous-time or discrete-time linear time invariant (LTI) control systems.
Ch Control System Toolkit supports most classical and modern control techniques through object-oriented programming based on a control class. It is simple and easy to use.
The new released Ch Control System Toolkit
added member functions
to compute a compensator's zero, pole, and gain;
the dominant pole based on the percent overshoot or damping ratio;
and characteristic information of step responses.
The modeling, design,
and analysis of control systems
can be
easily performed on line using a Web browser without any
software installation, configuration and computer programming.
A control system can be modeled in the form of transfer functions, zero-pole-gain, or state-space. Ch Control System Toolkit can perform analysis and design of control systems in both time and frequency domains with extensive graphical plotting capabilities. In addition, it can seamlessly interface existing C/C++ code in either source code or binary libraries without re-compilation.
Below is the root locus plot from a program using Ch Control System Toolkit
running
across different platforms.
Ch Control System Toolkit contains the following major features:
-
C/C++ Compatible
Different from other similar control software
packages, programs written in
Ch Control System Toolkit can
seamlessly.
interface
existing C/C++ code in either source code or binary static/dynamical libraries without
re-compilation.
-
Object-Oriented
Implemented as a class,
Ch Control System Toolkit is object-oriented.
-
Embeddable
With Embedded Ch,
Ch programs using Control System Toolkit can be embedded
in other C/C++ application programs.
-
Web-Based
Using
the Web-based control design and analysis system
in the Ch Control System Toolkit,
design and analysis of control systems
can be performed
through the Web
using a Web browser
over the internet without
any software installation, system configuration and programming.
-
Model Building
Support multiple model representations such as
state-space models, transfer function, and zero-pole-gain
models both for continuous-time and discrete-time
linear time invariant (LTI) systems.
When a system is created using one of these three
models, the Ch Control System Toolkit automatically converts
it to other two models internally and keeps the information
of these three models for user to retrieve.
-
Continuous/Discrete Systems Conversions
Provide the capability of converting from continuous to discrete,
discrete to continuous, and discrete to discrete system.
-
System Interconnecting and Reduction
Construct arbitrary complex system models given
in a block diagram form by using interconnecting
member functions.
-
Time Domain Analysis
Compute the time responses to arbitrary inputs and
initial conditions for both SISO and MIMO systems.
The typical inputs are step and impulse inputs.
The output responses can be displayed by either a plot
or a data set.
-
Frequency Domain Analysis
Generate commonly used frequency response plots of
Bode, Nyquist and Nichols plots. Calculates the bandwidth,
DC gain, gain and phase margins of a SISO system
for system dynamics and stability analysis.
-
Root Locus Design
Calculate and plots the root locus of a SISO system.
-
Controllability and Observability
Construct the controllability and observability matrices.
Determines the controllability and observability of systems.
Calculates the controllability and observability grammians of
a state-space model.
-
State-Space Design
Find the control-law and estimator that will
allow the user to select
a set of pole locations for a satisfactory system
dynamic response.
-
Optimal Control System Design and Equation Solvers
Calculate LQ-optimal gain for both continuous and
discrete systems.
Solves continuous and discrete-time Lyapunov equations.
-
Plotting Utilities
Provide many plotting functions to allow output visually displayed or exported as external files with a variety of different file formats. They can also readily be copied and pasted in other applications such as Word in Windows.
Ch Control System Toolkit is based on Ch Professional Edition.
It is free for academic use and costs $299 for commercial or personal use.
It can run across platform in Windows 95/98/Me/NT/2000/XP/Vista, Linux, Mac OS X, Solaris, HP-UX, FreeBSD, and QNX.
