abstract
The dynamics of tensegrity systems have their simplest mathematical form when the realisation is non-minimal. In this article, the simplicity of this structure is exploited to design controls. A Lyapunov-based approach creates a non-linear feedback control law exploring the tools of linear algebra due to the linearity of the model on a new set of transformed control variables. Explicit solutions are given for different choices of norm minimisation of the instantaneous control. The theory is illustrated through numerical simulations of simple tensegrity structures.
