Abstract
Systems and methods for actively isolating a payload from a disturbance. In one example, a seat system for a vehicle includes a seat, a support structure including an actuator configured to move the seat about a pivot axis at a command angle, a sensor positioned to detect vehicle movement, and a controller configured to determine a vehicle roll angle based on an input from the sensor, generate a variable gain based at least on a vehicle roll acceleration determined from the input, wherein the variable gain modulates a gain of a band-pass filter having a fixed bandwidth, generate a command signal based at least on the vehicle roll angle, the controller configured to adjust a magnitude of the command signal relative to an amplitude of the input and apply the band-pass filter, and provide a force command to the actuator to move the seat at a desired command angle.
