Abstract

This paper proposes a hybrid fuzzy P+I controller for a servo-pneumatic machine to perform and monitor tests on biomechanical devices, such as orthopaedic prosthesis. The methodology followed is based upon the CompactRIO®, a real-time platform, and the system was fully programmed using LabVIEW language. Separate algorithms of a PI, proportional fuzzy and hybrid fuzzy P+I controllers were developed and compared. The performance of the overall system has already been tested and the experimental results for position control show that the PI controller can reach 2 µm of accuracy but with a very slow rise time. However, the same accuracy can be achieved with Hybrid Fuzzy P+I controller, although with a fast rise time and neglected overshoot. The authors can conclude that this proposal can successfully overcome unknown nonlinear parameters of the pneumatic system and has high position control accuracy.
