This paper presents the mechanical details regarding a new control test rig for laboratory use. A variable geometry turbocharger is this system central part. In this paper it will be shown how this rotating machine can be decoupled from the internal combustion engine and fitted in a testbench where a computer emulates the vehicle’s motor. In order to accomplish this, a dozen of mechanical parts were designed and built. In addition, a set of sensors and actuators was adapted to the system. This article will show the final result of a system that will be used to test several different control strategies, with relevance given to the coefficient diagram method.
