Study Concerning the Hysteresis of Pneumatic Muscles
A known phenomenon during the contraction/expansion cycles of pneumatic muscles is the occurrence of hysteresis, caused by the elasticity of their component materials. The inherent hysteresis manifest in pneumatic muscles increases the non-linearity of the systems they are included in and consequently the complexity of the related control systems. The paper discusses a number of experimental results obtained for the hysteresis related behaviour of a small size Festo pneumatic muscle, where the specific hysteresis loops were highlighted via isotonic testing.
