Nonlinear Inductor

Nonlinear Inductor

An implementation of a nonlinear inductor where inductance depends on current. A tanh function defines the nonlinear flux-current relationship. The flux saturates for large currents, which can occur, for example, in iron core inductors.

Solenoid

Solenoid

A solenoid with a spring return. The solenoid is modeled as an inductance whose value L depends on the plunger position x. The back emf for a time-varying inductance is given by:

Heat Sink Using PS State-Space Block

Heat Sink Using PS State-Space Block

How the PS State-Space block can be used to model a heat sink in air. The heat sink is modeled as rods with distributed masses along the length of the rods fixed to a base. The rods extend from the surface that undergoes conduction along its length and convection with air in the direction perpendicular to its length.
