Abstract
The design and implementation of a novel fuzzy supervisory control approach for the motion control of a seismic shake table is addressed in this work. For this purpose, a single degree of freedom laboratory-scale electric shake table was developed. The control scheme comprises two loops: a PI inner loop and a fuzzy outer loop as the supervisor. Three separate supervisory controllers are proposed and implemented in the shake table and their performance in tracking two real earthquakes is assessed via extensive shake table testing. The test results reveal the effectiveness of the fuzzy supervisory controller in reducing displacement and acceleration tracking errors.
