Turbochargers are used to increase engine manifold air pressure. Control of intake manifold pressure is crucial issue which is done through the speed control of turbocharger, but since it is difficult to directly control the speed of the turbocharger, it is done indirectly through a gate that called the waste gate, which is located in the engine outlet and turbocharger’s turbine inlet. One of the most common control methods for control of turbocharger is the gain scheduling control. This method design in parameter look-up table, supervisor and system subsection to control turbocharger performance. The performance of control loop can be evaluated with accuracy of considered model and designed controller. In this paper, the engine model with the turbocharger has been created in the GT-POWER software, then, by defining the input and output parameters in the GT-POWER model, the model is coupled with MATLAB software to controller design. In the next step, two methods have been developed to design the controllers for the gain scheduling control method. Eventually, effectiveness of turbocharger control using gain scheduling control is shown.
