Abstract
A control system provides steering control commands to a steering actuator of a steering device on a piece of towed marine equipment. A memory in the control system stores setpoint data including positional values for a desired position of the piece of towed marine equipment. A control module is configured to receive the setpoint data, receive process data representing a calculated actual position of the piece of towed marine equipment; and calculate a control command for the steering actuator of the steering device based upon the setpoint data and the process data. A disturbance adjustment calculation module is configured to combine a disturbance value based upon a measured disturbance with a value of the process data and output a disturbance adjustment value. A correction calculator module adds the disturbance adjustment value to the control command to create an adjusted control command for transmission to the steering actuator.
