Abstract

ELECTROMECHANICAL ACTUATORS (EMAS) ARE OF INTEREST FOR APPLICATIONS WHICH REQUIRE EASY CONTROL AND HIGH DYNAMICS. THE MAIN GOAL OF THIS PAPER IS TO MODIFY AN EXISTING FIN CONTROL EMA HARMONIC DRIVE SYSTEM WITH CLASSIC CONTROLLER TO MEET PRESCRIBED STABILITY AND PERFORMANCE ROBUSTNESS CONSTRAINTS. FOR THIS PURPOSE, THE EXPERIMENTAL IDENTIFICATION, UNCERTAINTY MODELLING, AND ROBUST CONTROL DESIGN OF A FIN CONTROL EMA SYSTEM WITH TIME DELAY ARE ADDRESSED. THE ROBUST CONTROLLER WAS DESIGNED BY TWO APPROACHES; THE FIRST IS A METHOD BASED ON COMPLEX KHARITONOV THEOREM WHICH NOT ONLY ROBUSTLY STABILIZES THE UNCERTAIN EMA SYSTEM WITH TIME DELAY, BUT ALSO MAINTAINS THE PRE-SPECIFIED MARGINS AND BANDWIDTH CONSTRAINTS. THE SECOND IS AN H¥&NBSP;THEORY BASED APPROACH. FURTHERMORE, THE DISCREPANCIES BETWEEN THE LINEAR MODEL AND THE ACTUAL SYSTEM, DUE TO IGNORED NONLINEARITIES, WERE ESTIMATED AS MULTIPLICATIVE UNCERTAINTY. SIMULATION AND TEST RESULTS PROVE THE SUPERIOR PERFORMANCE OF THE EMA WITH H∞ CONTROLLER OVER THE ORIGINAL EMA AND THE ROBUST EMA WITH KHARITONOV'S CONTROLLER, ALTHOUGH BOTH CONTROLLERS FULFILLED THE EMA SYSTEM'S PERFORMANCE.
