Hello friends! Today, we will discuss fault detection of a gas turbine in MATLAB and Simulink. The aim is to understand how measurements, a reference model and decision logic can work together to identify abnormal behavior. We will move from the physical system to residual calculations, then examine how to test a detector without confusing a simulated alarm with a validated machine-protection system. The original project contains a useful collection of scopes, delays, summing blocks and alarm indicators. However, some block names and explanations need correction. In particular, a mu-law signal compressor is not an air compressor, and a piston-engine power-stroke model does not become a gas-turbine model merely by changing its displayed name. We will retain the original screenshots as a his ...
