PID based Dynamometer used in engine test [ READ ]
Pradnya Kulkarni, Chandrakant Kadu
In today’s modern world, IC engines are tested for its performances such as speed & torque developed. To test the performance of these engines dynamometer controllers & associated instrumentation is used. This paper describes how PID controller for dynamometer provides a mean for testing engine in desired & controlled conditions such as speed, torque with respect to throttle position in order to test engine. PID acts as dynamometer controller. For implementing this controller different test scenario can be simulated in lab for performing engine test with help of eddy current dynamometer. This paper presents the implementation aspects of PID in DDC using Labview and engine performance analysis in GUI( Graphical user interface).The simulation results revealed that the engine process is best tuned using Z-N technique through Labview. Finally, results extracted from simulation are displayed in GUI of test engine.
