Bond graph models for electromagnetic actuators
Abstract
Rotary and linear electromechanical actuators are often used as the effectors for controlled systems and they often are important contributors to the dynamic response of the complete system. A generalized bond graph model for such actuators is developed which represents the three major types of forces or torques generated when coils, low reluctance elements and permanent magnets interact. A wide variety of actuators can be modeled by versions of the basic bond graph which is simplifiable when some effects are negligible. The bond graph aids in understanding algebraic manipulations necessary to put the constitutive laws into forms compatible with other elements of the system for simulation or analysis.
