Abstract_ Background The design of an optimal neuroprostheses controller and its clinical use presents several challenges. First the physiological system is characterized by highly inter-subjects varying properties and also by non stationary behaviour with time due to conditioning level and fatigue. Secondly the easiness to use in routine clinical practice requires experienced operators. Therefore feedback controllers avoiding long setting procedures are required. Methods The error mapping controller EMC here proposed uses artificial neural networks ANNs both for the design of an inverse model and of a feedback controller. A neuromuscular model is used to validate the performance of the controllers in simulations. The EMC performance is compared to a Proportional Integral Derivative PID included in an anti wind-up .
