A propulsion control system has an electric motor configured to generate an axle torque in response to a final torque command, and has a motor constraint that specifies a maximum torque. A motor controller is configured to generate the final torque command in response to an intermediate torque command and a distributed power limit command. An open-loop function in supervisory controller is configured to calculate an initial torque command vector in response to a driver torque command, calculate an intended operating vector by mapping the initial torque command vector into a multidimensional power space, generate the intermediate torque command by clipping the intended operating vector in response to the motor constraint, generate a constrained command vector by clipping the intended operating vector in response to the motor constraint and a plurality of energy storage constraints, and generate the distributed power limit command in response to the constrained command vector.
