A CASE STUDY OF OPTIMAL INPUT-OUTPUT SYSTEM WITH SAMPLED-DATA CONTROL: DING ET AL. FORCE AND FATIGUE MUSCULAR CONTROL MODEL

The objective of this article is to make the analysis of the muscular force response to optimize electrical pulses train using Ding et al. force-fatigue model. A geometric analysis of the dynamics is provided and very preliminary results are presented in the frame of optimal control using a simplified input-output model. In parallel, to take into account the physical constraints of the problem, partial state observation and input restrictions, an optimized pulses train is computed with a model predictive control, where a non-linear observer is used to estimate the state-variables.
