Enhanced Dynamic Model of Pneumatic Muscle Actuator with Elman Neural Network
Figure 6
Proposed identification scheme for the estimation of disturbance term  using a neural network. In the scheme,  is valve control signal vector,  is th actuator output variable,  is th model output variable,  is disturbance term,  is disturbance term estimation,  is disturbance term estimation error, and  is neural network input vector.
