Abstract

This paper examines the effects of force equalisation in a four lanes torque-summed architecture that was designed to drive a control surface similar to that on the Sea Harrier, following two motor failures. PID control was implemented to control the common output shaft. Force equalization was assessed in the presence of inherent internal motors parameters deviations as well as inherent drift in feedback transducers. 3-phase motor models were utilised to cater for the torque ripple effects. Force equalization was proven to be most effective on deviations due to drift in potentiometer readings.
