Estimating Ground Inclination Using Strain Sensors with Fourier Series Representation
(a) Reference ankle angle and actual angle of an unloaded AFO give a control error in inclinations. Below: Ankle position of a biological foot during mid-stance while using compensating keels with resulting control error . (b) The keel angle is chosen so that and (c) is the error shown as the angle between the actual orthosis and the vertical “desired” direction (dotted).
