MSC.EASY5 Simulation Tools to Model and
Optimize Electric Systems
OVERVIEW
The MSC.EASY5 Ricardo Electric Systems Library V1.0, developed by
Ricardo Inc., a leading expert in powertrain research and
development, helps you solve more of your electric systems design
problems through modeling and simulation than any other software on
the market. The Electric Systems Library provides tools to develop
concepts into designs. For experts in electric machines, as well as
application-oriented users from other disciplines, complete systems
can be modeled, analyzed, and simulated quickly and flexibly.
The Electric Systems Library was designed for engineers by
engineers. It focuses on the kinds of results you want to achieve in
modeling the complex dynamics of electric systems. While the
underlying components utilize fundamental electrical, magnetic,
mechanical and control system principles, they are designed for
straightforward use at the system level. Tools are supplied to model
AC and DC machines, power electronics, control systems, electrical
energy storage, and networks at multiple levels of complexity. High-
level models are built and exercised quickly, with a user-friendly
migration path to more detailed models of higher fidelity.
ELECTRIC SYSTEMS SOLUTIONS
Electric System components are easily connected to facilitate the flow
of electrical energy into rotational mechanical energy and vice versa.
The scope of the component models is focused on localized systems,
such as in automotive and industrial applications, as opposed to
distributed utility systems connected with a large power grid. Motor -
generator components and the power electronic infrastructure to
support them are available. This expedites the modeling of hybrid
vehicle systems.
CAPABILITIES
Easily incorporates electric systems into
powertrain models
Includes flexible control strategies for all
machines
Parameterizes components according to
electromagnetic characteristics or
mechanical performance specs
Incorporates simple, user-friendly electric
component interconnection
Simulates with efficient high-frequency
switch-mode electronics or continuous
emulation
Utilizes short-term simulations that can
examine details like pulsation effects, while
faster long-term simulation elucidates
overall performance
Incorporates your own Fortran or C code
into the model
Develops complete virtual prototypes by
interfacing MSC.EASY5 models to
mechanisms modeled in MSC.ADAMS and
DADS
®
, and control systems in SIMULINK
®
BENEFITS
Model complex electric systems without
having to write code or derive equations
Build complete virtual prototypes of Hybrid
Electric Vehicles by combining components
from the Electric Systems, Powertrain and
Fuel Cell libraries
Achieve fast simulations using efficient
integration methods optimized for highly
nonlinear and discontinuous events
Further integrate your subsystems through
the modular machine/controller/electronic
combinations
Collaborate better by sizing machines
before final design details are available

The MSC.EASY5 model shown above represents a multiple voltage electrical system typically used in a
mild hybrid vehicle. A 14V system is retained to drive light electrical loads such as, dashboard lights,
radio, etc. The induction motor, used to provide parallel power to the drivetrain, requires significant
power that cannot be driven using 14V. A DC-DC converter generates 42V from the 14V battery. MSC, MSC., the MSC[x]Software logo, Simulating Reality, and the names of the MSC.Software products and services referenced

SAMPLE APPLICATION
A basic goal of this library is to represent a level of complexity
sufficient for the overall system without burdening the user with
unnecessary detail. When designing HEV systems, you may
need a machine to deliver motoring torque in some
circumstances and brake acting as a generator in others.
Knowing only the stall torque, rated speed or power, and an
estimate of the maximum current, a brushless permanent
magnet machine can easily be incorporated. Integrating the
machine, inverter and controller can easily be accomplished,
as shown below.
The simulation results pictured below show full four-quadrant
operation. Rated (stall) torque is available at low speed in either
direction and constant power is available at higher speed in
either direction.
After establishing the basic results, features can be
systematically added, such as a more detailed electric supply
network and switch-mode power electronics already built into
the inverter. It is in this way that ideas can evolve from the
concept stage into final design.
MODEL PARAMETRIZATION
Flexibility has also been designed into the parameterization of
many of the components in the Electric System Library. A
machine, for example, is characterized by a list of data in
terms familiar to an electrical engineer, such as resistance and
inductance. The same machine is also available in the library in
a form requiring data more familiar to a powertrain engineer,
such as speed and torque, rather than detailed electrical
parameters.
