Zetacon
Corporation will be introducing a family of multi-chip control
modules powered by CogniSim. The first of which, the sensorless
induction motor control MC2M, will be available in Q3 2004.
These
credit-card size modules provide designers the ability to provide
advanced control of power switches with a wide range of control
objectives. Zetacon’s proprietary control architecture, all firmware,
is designed to operate from a common hardware multi-chip module. This
common foundation allows a designer fast access to advanced control
normally requiring years of development effort, testing and expense to
achieve.
The Multi-chip
Module will be available in both an evaluation version and a production
version. The evaluation version contains an embedded web-server with
an Expert System web-page enabling the designer quick access to all
specific control parameter interfaces with a simple Ethernet connection
to a PC. The production version is designed to support applications
where the embedded web server is not required. In this case, control
parameter setup is achieved through a hardware interface to the user's
application.
Embedded
Simulation Capability
Based on CogniSim,
each controller contains a real or quasi-real time embedded simulation
of the type of load being controlled, and includes additional embedded
simulation capabilities for evaluation and test purposes, the specifics
varying by application. This feature allows the designer to operate in a
closed loop-back mode, wherein the power circuit gating commands are
generated as if the MC2M were connected to a real load.
During evaluation, this powerful loop-back embedded simulation allows
the designer the ability to verify other system design operations in a
virtually real environment. In production, the loop-back capability
allows the designer’s circuitry to be tested without actual load
hardware being required.
Sensorless Induction Motor Control - The Premier Solution
The first MC2M
to be introduced is a Sensorless Induction Motor Control System which
provides all of the control and support functions necessary to implement
a fully functional sensor-less induction motor drive system. This system
will provide very advanced direct torque control, operate at a
processing rate of about 5 microseconds, and deliver the motor control
benefits detailed in the Zetacon Motor
Control section.
This MC2M module, when coupled with a standard three-phase
voltage-source inverter power circuit, and some control interfaces,
allows the designer an economical design suitable for evaluation and
production use that eliminates years of hardware and software
development effort.
The
MC2M Roadmap:
While the Sensorless
Induction Motor Control System is the first of the family of MC2Ms
to be introduced, the following plan outlines the timing for the
introduction of additional MC2Ms for both motor control and
power conditioning applications.
