Abstract

• In this report we present the results of an in-depth experimental investigation regarding the Key-On control problem of a double magnet Electro Mechanical Valve Actuator (EMVA) with aimed at solving the first lift manoeuvre of the engine valve. Before to start the engine, the engine control unit requires to put the valve in close/open position and since the armature stays at central position far from magnets a high current would be required to produce enough magnetic force to catch the valve. The closing/opening of the valve at key-on is an important issue for an EMVA-based camless engine technology. Control engineering must deal with a strong complexity to assure the right performance during this manoeuvre increasing the reliability of new engine technology. Key-on control law is designed based on energy control aimed at seeking application requirements. The main result is that increasing the energy by means of controlled pump, friction energy lost can be compensated, locating the valve near to the coil boundary, achieving a target region faster which means, a short catching time. Key-on control performance is characterized numerically via energy analysis for each value of controller gain. Moreover, good agreement between theoretical results and real experimentation is achieved. (literal)
