Methods and apparatus to target engine operating cycle conditions for clearance control

A system comprising:

• at least one memory;
• programmable circuitry;
• and
• instructions to cause the programmable circuitry to:
• determine a current operating clearance of a gas turbine engine including a first motor coupled to a first rotatable component and a second motor coupled to a second rotatable component;
• identify one or more parameters of a model of the gas turbine engine for modification based on a difference between the current operating clearance and a desired operating clearance of the gas turbine engine;
• and
• modulate power to at least one of the first motor or the second motor based on the identified one or more parameters to satisfy the desired operating clearance and maintain a thrust of the gas turbine engine.
