    摘要： Presented is a system and method for controlling an actuator in a multirate control system using an integrated upsampler and filter, comprising an incremental command limiter for changing a command from a first control system into a limited incremental command in a second control system, a lead-lag filter for filtering the limited incremental command to attenuate high frequencies, and a feed forward path for reducing phase loss in rate output signal at low frequencies. In embodiments, a command position signal received at the sampling rate of the first control system is interpolated into incremental command position signals at the sampling rate of the second control system. Position error signals and rate error signals from the devices being controlled are used as feedback to further stability the control loops.

    摘要： The method and system for automatically controlling a path of travel of a vehicle include engaging an automatic control system when the security of the onboard controls is jeopardized. Engagement may be automatic or manual from inside the vehicle or remotely via a communication link. Any onboard capability to supersede the automatic control system may then be disabled by disconnecting the onboard controls and/or providing uninterruptible power to the automatic control system via a path that does not include the onboard accessible power control element(s). The operation of the vehicle is then controlled via the processing element of the automatic control system. The control commands may be received from a remote location and/or from predetermined control commands that are stored onboard the vehicle.
