Intelligent control approaches for tilting railway vehicles

Fuzzy logic has proved to be an effective methodology for many control system applications as it mimics human control logic. This paper presents the work on fuzzy control design for achieving improved local-per-vehicle tilt performance. Two fuzzy-based nulling-type tilt control schemes are discussed, a Fuzzy-PI, and a PID with fuzzy correction. The performance of the control schemes is assessed via appropriate computer simulations and a recently proposed tilt control assessment method.
