  • Publication number: 20230406473
    Abstract: The vessel azimuth control apparatus has an azimuth control unit that outputs a steering-angle command signal for making a vessel turn to an azimuth to which the vessel should travel, based on an azimuth command signal generated by an azimuth command generation unit, a yaw-angle signal, and a yaw-angular-velocity signal, a steering-angle control unit that controls a rudder based on the steering-angle command signal, and a control gain adjustment unit that has a calculation feasibility determination unit for determining feasibility of calculation of frequency responses, based on the yaw-angle signal and the yaw-angular-velocity signal, and that calculates respective frequency responses of the yaw-angle signal and the yaw-angular-velocity signal for the steering-angle signal, when the calculation feasibility determination unit determines that calculation of frequency response are feasible, and then adjusts a control gain of the azimuth control unit.

  • Publication number: 20220315193
    Abstract: The objective is to obtain an azimuth control apparatus and an azimuth control method that require no excessive memory capacity and calculation time for information processing and can cope with a disturbance by adaptively adjusting a control gain while calculating changing vessel parameters online. The vessel azimuth control apparatus has an azimuth control unit that outputs a steering-angle command signal for making a vessel turn to an azimuth to which the vessel should travel, based on an azimuth command signal generated by an azimuth command generation unit, a yaw-angle signal, and a yaw-angular-velocity signal, a steering-angle control unit that controls a rudder based on the steering-angle command signal, and a control gain adjustment unit that calculates respective frequency responses of the yaw-angle signal and the yaw-angular-velocity signal to a steering-angle signal outputted by a steering-angle detection unit and then adjusts a control gain of the azimuth control unit.

  • Patent number: 9108823
    Abstract: An elevator safety control device realizing suppression in increase in cost and labor hour of installation and maintenance without deteriorating safety of normal safety control functions even when a plurality of safety control functions are provided. The elevator safety control device includes an independence assurance unit assuring independence of a safety control function. The independence assurance unit assures independence of each of the safety control functions by monitoring whether or not the safety control function accesses a memory other than a permitted region. When the independence assurance unit detects an access to the memory other than the permitted region by a predetermined safety control function, the elevator safety control device stops a car.

  • Patent number: 8959405
    Abstract: Each of a master node and a slave node has a safety data processing unit and a high reliability communication unit. At the time of transmission, the safety data processing unit creates a safety data packet including data about safety and the high reliability communication unit creates a communication data packet including the safety data packet and transmits the communication data packet a predetermined number of times. At the time of reception, the high reliability communication unit acquires and outputs a safety data packet by determining one of one or more communication data packets having the same contents which it has received properly as an effective packet, and the safety data processing unit analyzes a state concerning the safety of a system on the basis of the data about safety acquired from the safety data packet.
