Diesel Engine Control and Protection Monitoring using PID Controller

This paper deals with the development of a Simulink model for the control, protection and monitoring system of a diesel engine. Various sensors and switches involved in the engine protection and monitoring systems such as throttle position sensor (TPS), lube oil pressure sensor (OPS), coolant temperature sensor (CTS) and idle validation switch (IVS) are discussed in detail. Then, a comparison study of the speed control of the diesel engine was done using P, PI and PID controllers. Finally, a mathematical model of the diesel engine is derived using the System Identification Technique. The results obtained by formulating an accurate mathematical model and a precise controller allow the operator to establish the required engine protection parameters such as the coolant temperature, oil pressure and the speed of the engine.
