Abstract
A method includes obtaining multiple parameters associated with operation of a turbine engine. The method also includes applying a model predictive control algorithm to the parameters to predict a future torque value of a shaft of the turbine engine, the future torque value indicating a likelihood of future shaft shear. The method further includes, in response to the future torque value being outside of an expected range, performing an action to reduce risk of the future shaft shear.
