Intelligent active force control of a human-like arm actuated by pneumatic artificial muscles

Robotic system driven by fluidic muscles is time-varying and exhibits high degree of nonlinearity due to the internal system behaviours and thus controlling it constitutes a major problem. This poses a great challenge to researchers to come up with suitable technique/s to control such system effecti...
