Claim of US Patent No. 10,954,877

1. An electric motor/generator controller for operating a motor/generator used as an auxiliary torque source/sink in a hybrid powertrain, the hybrid powertrain including an internal combustion engine that operates in a firing sequence, the motor/generator controller comprising:a matched basis function control module arranged to generate a control signal for the electric motor/generator; and
a secondary path dynamics module arranged to determine a dynamic response of a secondary path, the secondary path being the response of the motor/generator to a motor/generator control signal, wherein the control signal of the matched basis function control module is affected by the determined dynamic response of the secondary path.
