Abstract
Systems and techniques for operating an active suspension system are discussed herein. The active suspension system can include a first suspension couple to a first wheel and a second suspension coupled to a second wheel, each suspension can include a first valve, a second valve, and an actuator. While a vehicle is traversing an environment, the vehicle can receive sensor data indicating an uneven surface is within a trajectory of at least the first wheel. A vehicle controller can determine a target position for the actuator of the first suspension, a target current to be generated at the first valve or the second valve and associated with moving the actuator from its current position to the target position, and a target voltage to be apply at the first valve or the second valve to generate the target current to compensate for a change in pitch and/or roll of a vehicle induced by the uneven surface. The vehicle controller can further determine a modified input voltage that causes the target current to be generated at a faster time than the input voltage.
