Ch Control System Toolkit 1.5 released

DAVIS, Calif., March 19, 200 – SoftIntegration, Inc., the leader of

scripting technology for ubiquitous computing, today announced the release

of Ch Control System Toolkit version 1.5. Ch is a superset of C interpreter

for scripting, 2D/3D plotting and numerical computing. Ch Control System

Toolkit is designed for modeling, design, and analysis of continuous-time

or discrete-time linear time invariant (LTI) control systems.

The new released Ch Control System enhances the Web-based control and

analysis capabilities. The modeling, design, and analysis of control

systems can be easily performed on-line as demonstrated below

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.

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.

* 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 costs

$499 for commercial and $199 for academic. It can run cross platform in

Windows 95/98/Me/NT/2000/XP, Linux, Mac OS X, Solaris, and HP-UX.
