  • Publication number: 20200127458
    Abstract: In a power storage system, a three-phase AC wire is connected to a three-phase AC power system. Power storage blocks, each of which includes a power storage module and a power conditioner, are connected in parallel to the three-phase AC wire. A system controller individually controls power storage blocks. The power storage modules each includes: a power storage unit; and a management unit that manages the power storage unit. The power conditioner includes a power converter and a controller. The power converter converts DC power discharged into single-phase AC power and outputs the converted AC power to two lines of the three-phase AC wire, or converts single-phase AC power received from the two lines of the three-phase AC wire into DC power and charges the power storage unit. The controller is connected to the system controller via a communication line and the management unit via a communication line.

  • Patent number: 10627834
    Abstract: An aircraft control device calculates trajectories of multiple aircraft that is member of a flight by use of a method such as Direct Collocation with Nonlinear Programming (DCNLP), in which an optimal solution is obtained by discretizing continuous variables. Nodes indicating the trajectory are calculated and set by substituting a discretized control variable of the aircraft into an aircraft equation of motion, or by use of other methods. Instead of calculating the trajectory of the aircraft as a continuous problem, discretisation reduces the calculation amount and time required for the trajectory calculation. The aircraft control device then determines, from among trajectories satisfying constraints corresponding to the role of the aircraft, an optimal trajectory based on an evaluation value obtained by an objective function corresponding to the role. Accordingly, the aircraft control device can calculate a more optimal trajectory corresponding to the role of the aircraft in a shorter time.

  • Patent number: 9233761
    Abstract: A flight path maker (FPM) and a target attitude relative to air display are displayed on a primary flight display (PFD), which is an integrated indicator. The target attitude relative to air display is a mark indicating a target attitude relative to air representing a target angle-of-attack and a target sideslip angle of the aircraft to achieve a target flight path. The PFD displays the relative difference between the FPM and the target attitude relative to air display and shows that the aircraft is flying in the target traveling direction when the FPM matches (is superposed on) the target attitude relative to air display. Thus, controlling with higher trackability than controlling performed based on a target attitude relative to ground is enabled.

  • Patent number: 9199723
    Abstract: A control system of an aircraft includes a computer that controls flight based on either a flight control law that controls flight by controlling the deflection angles of control surfaces or a control surface/thrust integrated flight control law that controls flight by controlling the deflection angles of the control surfaces and engine thrust, and a control surface failure/damage detection device. If malfunctioning of the control surface(s) is detected, the deflection angles and the rates of change of the deflection angles of the control surfaces are calculated based on the detection result, and the necessity of switching from the flight control law to the control surface/thrust integrated flight control law is judged by judging whether or not the calculated deflection angles or rates of change of the deflection angles exceed an acceptable range of change.
