Modeling Electronic and Electromechanical Systems

With SimElectronics you build a model of a system just as you would assemble a physical system . The symbols in your model are consistent and conventional, and you connect them with physical connections. SimElectronics employs a physical network approach, also referred to as acausal modeling, to model building: components (blocks) corresponding to physical devices such as photodiodes, transistors, and motors, are joined by physical connections (lines) that transmit power. This approach lets you describe the physical structure of the system rather than deriving and implementing the equations for the system.

From your model, which closely resembles a schematic, SimElectronics automatically constructs the differential algebraic equations (DAEs) that characterize the behavior of the system. These equations are integrated with the rest of your Simulink® model, and the DAEs are solved directly.

SimElectronics libraries provide more than 55 models of electronic and electromechanical components, including models of motors and op-amps, that you can combine to represent commercially available components. The blocks in SimElectronics support two different workflows - you can set the values of your parameters by pulling them directly from industry data sheets, or you can import SPICE circuits and device models directly into SimElectronics (currently limited to bipolar transistor, JFET, basic diode, sources, and passive SPICE components).

You can use the sensor blocks to measure any electromechanical variable, such as voltage, current, angular velocity, or torque, and then pass these signals into standard Simulink blocks. Source blocks enable Simulink signals to assign values to electromechanical variables. Sensor and source blocks let you connect control or signal processing algorithms developed in Simulink to a SimElectronics network.
