Self-stability in Biological Systems — Studies based on Biomechanical Models

摘要: Mechanical properties of complex biological systems are non-linear, e.g. the force-velocity-length relation muscles, activation dynamics, and geometric arrangement antagonistic pair muscles. The control such is a highly demanding task. Therefore, question arises whether these mechanical muscle-skeletal system itself able to support or guarantee for stability desired movement, indicating self-stability. Self-stability single joint were studied based on eigenvalues equation motions basins attraction analysed using Lyapunov functions. In general, we found self-stability in muscle contractions (e.g. frog, rat, cui), human arm leg movements, spine even co-ordination movements as tennis basketball. It seems that may be general design criterion not only but also motor control.
