Abstract:
1. A powertrain comprising: a plurality of gear sets; a plurality of clutches; a plurality of rotatable members; a plurality of physical torque actuators each configured to output a corresponding total control torque, wherein the corresponding total control torque from at least one of the torque actuators is used to achieve a target value that is a torque value of a physical target of the powertrain, and wherein the physical target is a member of one of the gear sets, clutches, or rotatable members; a controller having tangible, non-transitory memory containing proportional-integral (PI) control logic, wherein a total control torque for the physical target is defined as a sum of a proportional and an integral torque term from the PI control logic for each of the at least one physical torque actuators used to achieve the target value, and wherein the controller is configured to:
