    • A system for controlling an air/fuel ratio of an internal combustion engine, including a feedback control loop having an adaptive controller (STR controller) that receives as inputs a desired value r and a controlled variable y output from the plant (engine) and an adaptation mechanism that estimates adaptive parameters. The STR controller calculates a feedback correction coefficient KSTR, as an output u based upon at least the adaptive parameters, for correcting a basic amount of fuel supply calculated by retrieving mapped data, prepared beforehand, such that the controlled variable y converges to the desired value r. The system is configured such that the controlled variable y is determined based upon the detected air/fuel ratio KACT and a desired air/fuel ratio KCMD so that the desired value r is a predetermined value. More specifically, the controlled variable is determined to be a ratio between the detected air/fuel ratio and the desired air/fuel ratio such that the desired value r is 1.0 or thereabout. With this arrangement, when the desired air/fuel ratio is changed or corrected frequently, the estimation of the adaptive parameters is not affected, thereby improving the stability of air/fuel ratio control.
    • 一种用于控制内燃机的空燃比的系统,包括具有自适应控制器(STR控制器)的反馈控制回路,所述自适应控制器(STR控制器)接收从所述设备(发动机)输出的期望值r和控制变量y作为输入, 估计自适应参数的适应机制。 STR控制器基于至少自适应参数计算反馈校正系数KSTR作为输出u,用于校正通过检索预先准备的映射数据计算的燃料供应量的基本量,使得控制变量y收敛到期望值 r。 该系统被构造为使得基于检测到的空气/燃料比KACT和期望的空气/燃料比KCMD来确定受控变量y,使得期望值r是预定值。 更具体地说,控制变量被确定为检测到的空气/燃料比与期望的空气/燃料比之间的比,使得期望值r为1.0或其附近。 通过这种布置,当期望的空燃比频繁地改变或校正时,自适应参数的估计不受影响,从而提高空/燃比控制的稳定性。

    • A fuel supply amount control system for an internal combustion engine having exhaust gas recirculation passage extending between the exhaust passage and the intake passage, and an exhaust gas recirculation valve arranged across the exhaust gas recirculation passage, for recirculating part of exhaust gases emitted from the engine to the intake passage, has an ECU which detects an actual valve lift amount of the exhaust gas recirculation valve, determines a desired valve lift amount of the exhaust gas recirculation valve, based on operating conditions of the engine, and controls the exhaust gas recirculation valve, based on determined the desired valve lift amount and the detected actual valve lift amount, when the engine is in a predetermined operating region where conditions for executing exhaust gas recirculation control are satisfied. A basic fuel supply amount is calculated based on operating conditions of the engine, and a correction coefficient for correcting the basic fuel supply amount, is set based on the actual valve lift amount and the desired valve lift amount, when the engine is in the predetermined operating region. The basic fuel amount is corrected based on the correction coefficient.

    • [Object] Conventionally, measures for securing stability of a ship when it is damaged are required.[Solution] The invention is characterized by having a remotely openable seawater inlet means provided to a lowermost watertight deck that forms a void space at the bottom of the ship. Thereby, when a side shell plate or the like of the ship is damaged and seawater enters the ship, the seawater that has entered the ship can be introduced into the void space by opening the seawater inlet means provided to the lowermost watertight deck, so that the void space, which usually provides a huge auxiliary buoyancy, can be made to function as a sort of a seawater ballast tank, whereby the ship's stability can be recovered.

    • The present invention relates to a traveling direction measuring apparatus usable as a pedestrian navigation system in locations where it is difficult to obtain high positioning accuracy such as inside buildings or around multistory buildings where a GPS cannot be used. An acceleration detecting section (1) detects 3-axes acceleration of the traveling direction measuring apparatus, which varies with the walking of the pedestrian. An acceleration data acquiring section (2) obtains 3-axes acceleration data repeatedly by the number of prescribed times or more, said 3-axes acceleration data varies with the walking of the pedestrian. A first gravity acceleration calculating section (3) calculates, when the pedestrian is walking with holding the traveling direction measuring apparatus in a generally fixed attitude, gravity acceleration by averaging acceleration data sets during several steps obtained by the acceleration data acquiring section (2). A first moving direction estimating section (4) estimates the moving direction of the pedestrian from frequency components corresponding to the duration of one step of the acceleration data sets projected on a plane perpendicular to the gravity acceleration calculated by the first gravity acceleration calculating section (3).
