Systems and methods for control of dissipation devices

A method for controlling a work machine comprising:

• determining, based on sensor data from a sensor system, to decelerate the work machine using an electric motor of the work machine;
• controlling, using a control loop, a load system to dissipate or store at least a portion of energy produced by the electric motor during deceleration;
• determining a charging current limit for a battery of the work machine;
• and
• activating a feed forward signal in response the determining to decelerate the work machine, wherein:
• the feed forward signal is based on the charging current limit and pre-activates the load system prior to the load system being required to dissipate energy from the electric motor in response to decelerating the work machine;
• and
• activating the feed forward signal causes the load system to begin receiving energy from the electric motor before the charging current limit of the battery is reached during deceleration.

A controller for a work machine comprising:

• a first control system configured to control operation of a load system of the work machine in response to a first signal indicative of a target power distributed to the load system, the load system configured to dissipate or store energy produced by an electric motor of the work machine during deceleration;
• a second control system comprising a feed forward function configured to output a second signal for control of the load system in addition to the first signal, wherein the feed forward signal pre-activates the load system prior to the load system being required to dissipate energy from the electric motor in response to decelerating the work machine and wherein the second signal is based on a charging current limit of an energy storage device of the work machine such that the load system is pre-activated to receive excess energy that cannot be absorbed by the energy storage device within the charging current limit;
• a switch configured to selectively activate and deactivate the second control system in response to an input;
• and
• a summing component configured to sum the first signal the second signal and produce a combined signal for control of the load system.
