METHODS AND APPARATUS TO PERFORM TORQUE BALANCE CONTROL OF CO-SHAFTED MOTORS
First Claim
1. A method comprising:
- calculating, by executing an instruction with a processor, a first torque value based on first phase currents of a first motor that is driving a shaft connected to a control surface;
calculating, by executing an instruction with the processor, a second torque value based on second phase currents of a second motor that is driving the same shaft;
determining, by executing an instruction with the processor, a first shared torque value based on the first calculated torque value and a first sharing factor;
determining, by executing an instruction with the processor, a second shared torque value based on the second calculated torque value and a second sharing factor;
determining, by executing an instruction with the processor, a torque error based on the first shared torque value and the second shared torque value; and
determining, by executing an instruction with the processor, a first torque adjustment associated with the first motor based on the torque error.

Abstract
Methods, apparatus, systems and articles of manufacture to perform torque balance control of co-shafted motors are disclosed. An example method includes calculating a first torque value based on first phase currents of a first motor that is driving a shaft connected to a control surface, and calculating a second torque value based on second phase currents of a second motor that is driving the same shaft. The example method also includes determining a first shared torque value based on the first calculated torque value and a first sharing factor, and determining a second shared torque value based on the second calculated torque value and a second sharing factor. The example method also includes determining a torque error based on the first shared torque value and the second shared torque value, and determining a first torque adjustment associated with the first motor based on the torque error.
