A mathematical model of the muscle active length-tension relationship has been developed. It integrates the functional basis of different muscle arrangements into a mathematical description of the contractile element. The model is complex enough to represent many of the mechanical and architectural properties of active muscle. Yet, it is simple enough that only two parameters (muscle fiber optimal length, muscle belly optimal length) are needed to scale the model to a specific actuator.
