Abstract
For normal quiet standing the ankle strategy is used for human posture. The musculoskeletic system can be viewed as an inverted pendulum stabilised by a feedback loop with the lambda control. Mathematical modelling of the musculo-skeletal system under lambda control is presented as a nonlinear system with time-delay in feedback. Necessary conditions of asymptotic stability and a practical analytic expression of the delay margin are presented. To authenticate the model, five subjects are experimented
