RCU501 KONGSBERG 康士伯 动力定位系统控制器独立动力定位系统通过传统的信号电缆和串行线与其他系统连接，如发电厂和推进器。综合动力定位系统通过双以太网LAN与其他KONGSBERG系统通信，如K-Chief(船舶自动化系统)和K-Thrust(推进器控制系统)。动力定位系统控制器计算推进器/螺旋桨施加的合力，以使船舶保持在原位。在位置保持操作中，K-Pos控制器可以在以下几种模式下工作，所有模式都具有特殊的特征:高精度控制:高精度动力定位系统控制在任何天气条件下提供高精度的位置保持，代价是功耗和机械及推进器的磨损。松弛调控:放松的动力定位系统控制更平稳地使用推进器，代价是位置保持精度。

触发电路的作用是给输出器件提供触发信号。固态继电器的输出电路是在腴发信号的控制下，实现固态继电器的通断切换。输出电路主要由输出器件(芯片）和起瞬态抑制作用的吸收回路组成，有时还包括反馈电路。固态继电器的输入电路是为输入控制信号提供一个回路，使之成为固态继电器的触发信号源。固态继电器的输入电路多为直流输入，个别的为交流输入。直流输入电路又分为阻性输入和恒流输入。阻性输入电路的输入控制电流随输入电压呈线性的正向变化。恒流输入电路，在输入电压达到一定值时，电流不再随电压的升高而明显增大，这种继电器可适用于相当宽的输入电压范围。

然而，这种类型的控制不能保证船舶将停留在其操作区域内，并且主要适用于无风天气条件。绿色DP控制:康斯伯格开发了一种独特的动力定位控制系统GreenDP控制，这减少了燃料消耗，因此也减少了一氧化碳2排放量减少了20%。绿色民主党控制保护船只，使其停留在指定的操作区域内。这种新方法基于预测船舶的运动，而不是根据当前条件采取行动，使用一种称为“非线性模型预测控制”的方法，该方法优化预测的船舶偏移，避免使用推进器。通过这样做，不会迫使船舶脱离其操作边界的小的和短期的干扰被“过滤掉”。这可以实现非常平稳的控制，大幅降低峰值负载，并显著减少推进器的磨损，这是康斯堡绿色船舶战略的一部分。

RCU501 KONGSBERG Kongsberg Dynamic Positioning System Controller Independent Dynamic Positioning System is connected to other systems such as power plants and thrusters through traditional signal cables and serial cables. The integrated dynamic positioning system communicates with other KONGSBERG systems, such as K-Chief (Ship Automation System) and K-Thrust (Thruster Control System), through a dual Ethernet LAN. The dynamic positioning system controller calculates the combined force exerted by the thruster/propeller to keep the ship in place. In position keeping operation, the K-Pos controller can operate in the following modes, all of which have special characteristics: high-precision control: high-precision dynamic positioning system control provides high-precision position keeping under any weather conditions, at the cost of power consumption and mechanical and thruster wear. Relaxed regulation: The relaxed dynamic positioning system controls the use of thrusters more smoothly, at the cost of maintaining position accuracy.

The function of a trigger circuit is to provide a trigger signal to the output device. The output circuit of a solid-state relay is controlled by a low-frequency signal to achieve on-off switching of the solid-state relay. The output circuit mainly consists of an output device (chip) and an absorption circuit that plays a transient suppression role, sometimes including a feedback circuit. The input circuit of a solid-state relay provides a loop for the input control signal, making it the trigger signal source of the solid-state relay. The input circuit of solid-state relays is mostly DC input, and some are AC input. The DC input circuit is further divided into resistive input and constant current input. The input control current of the resistive input circuit varies linearly and positively with the input voltage. Constant current input circuit, when the input voltage reaches a certain value, the current no longer increases significantly with the increase of voltage. This type of relay can be suitable for a relatively wide input voltage range

However, this type of control cannot guarantee that the ship will stay within its operating area and is mainly applicable to calm weather conditions. Green DP Control: Konsberg has developed a unique powertrain positioning control system called GreenDP Control, which reduces fuel consumption and therefore reduces carbon monoxide emissions by 20%. The Green Democratic Party controls and protects ships to stay within designated operating areas. This new method is based on predicting the motion of ships, rather than taking action based on current conditions, using a method called “nonlinear model predictive control” that optimizes the predicted ship offset and avoids the use of thrusters. By doing so, small and short-term disturbances that do not force the ship to deviate from its operational boundaries are “filtered out”. This can achieve very smooth control, significantly reduce peak load, and significantly reduce propeller wear, which is part of the Konsberg Green Ship Strategy.
