An active suspension system includes a relative slow-responding force bias eliminator (such as a pneumatic actuator) and a relatively fast-responding actuator (such as an electromagnetic actuator) that together support a plant (such as a truck seat or vehicle cabin). The system also includes a load-unload detector (which may be a physical or virtual detector) to detect a loading or unloading of the plant. When such a loading or unloading is detected, the system causes the force bias eliminator to respond quickly (e.g., as quick as possible) while controlling the fast-responding actuator so as to preserve the available energy for operating the actuator (e.g., so as to keep the fast-responding actuator from consuming all of its available energy) prior to when the force bias eliminator can respond.
