A quarter-car model of a vehicle is shown with an idealized actuator capable of generating any control force, F_c.

(a) Construct a bond graph model, identify positive directions, and assign a power convention.

(b) A voice coil actuator with winding resistance, R_w, is to be installed as the force actuator to replace the idealized control force. The actuator will be voltage, e_c
, controlled. Include the force actuator in the quarter-car model and construct the overall bond graph model.

winding resistance, Rw coil length, l permanent magnetic with flux density B transduction constant T = BL force, F = Ti
