Abstract:

This program develops a practical design procedure for turbine engine control systems based on multivariable control theory. This volume describes a practical procedure for experimentally obtaining high-fidelity linear engine models from frequency response measurements. This procedure satisfies the modeling requirements for high-bandwidth control systems which are needed in the future for better regulation of surge margins and disturbances. A dynamic transfer matrix model of the GE-J85-13 engine is obtained at three engine operating speeds. The instrumentation is described for obtaining tape-recorded engine responses. Fourier filtering and servoanalysis techniques are demonstrated. An algorithm is described for identifying dynamic states and transfer functions from frequency responses.
