PhiSim

A multidomain physical systems modeling with Simulink from Mathworks

PhiSim is a modeling and simulation environment for physical systems using Matlab-Simulink and dealing with physical system modeling. PhiSim works in both closed and open loop modes. Il allows for creation of models and their controls in a multiport environment. More flexibility is provided since modeling with a limited number of elements is possible in order to simplify complex systems and therefore non-specialists can manipulate the models.

PhiSim includes a set of tools designed for system specialists as well as several libraries and utilities to facilitate the process of controlled systems modeling. In addition to existing libraries, users can personalize them by adding configurable components and adjust the models in order to apply them to any physical system.

PhiSim for Simscape MathWorks

PhiSim includes dedicated libraries, tools and utilities that facilitate modeling and simulation of dynamic control.

In partnership with Mathwoks we are working on Simscape libraries, starting with thermal fluids applications.

We also offer services covering the porting of existing models to Simscape.

Other simulation environments

From our expertise, we also realize benefits modeling physical systems from or to other environments and languages such as Amesim, Modelica and Dymola.

Modeling environment

PhiSim and its libraries have been developed in Matlab/Simulink environment. Nevertheless models are compatible with other technologies such as Simscape, AMESim and Dymola, thanks to the code generation feature offered by MathWorks products. On request, the models and the libraries can be translated into the native language of these environments.

Multi-domain libraries

Multi-domain system libraries are available to create models by combining and customizing the basic polymorphic elements:

  • 0D/1D mechanics
  • Electrical power systems
  • Thermal
  • Thermal fluids (one phase liquid and gas, two phases, moist air, combustion mixture and gas mixture)
  • Hydraulics

Application libraries

Our libraries are configured per application and contain all components to represent any system and subsystem, as well as standard models with their controls. The modular conception of the models assures quick assembly of the different subsystems to simulate the full system fast and accurately.

Vehicle System Dynamics

phisim_dynamics

Vehicle System Dynamics library has been developed to create models of suspension and pneumatic chassis, power-steering and braking systems. Different levels of complexity are available (1D to 3D representations). When the dynamic vehicle model is integrated in a complete vehicle model, interactions among all the control systems embedded can be validated.

Powertrain Transmission

phisim_powertrain

Powertrain Transmission is a platform dedicated to validate transmission architectures and to optimize power train control systems in order to achieve consumption and pollution standards. All propulsion systems: fuel, electrical and hybrid, are considered. The library also includes mechanic models (gearbox, transmission clutch, differential, brake, etc), simplified engine representations, electrical models (electrical machines and batteries) and environment elements (driver, driving cycle, etc)..

Cooling System

phisim_cooling

The Cooling System library is designed to create models of a complete cooling system in a vehicle. It includes the heater and its cooling system as well as a group of controlled components (pump, thermostat, controlled valves). Based on thermo-fluid equations, this library is able to calculate temperature distribution, flows and pressure existing anywhere in the circuit.

Air Conditioning System

phisim_air_conditioning

The Air Conditioning System library allows for conception and validation of AC systems including cold loop, multi-area cabin model and control system. This library is designed for static and dynamic applications. Calculations of the temperature distribution in the cabin, the air flow and the pressure in the circuit are based on thermo-fluid equations.
