摘要： An electrical power system comprises at least one synchronous generator (101), a signal transducer (102) for producing an amplitude signal indicative of the amplitude of generator voltage, and a controller (103). The signal transducer and the controller are parts of a voltage control loop for controlling the excitation of the synchronous generator on the basis of the amplitude signal and the reference amplitude. The voltage control loop comprises a band-rejection filter (104) or another signal conditioning device for suppressing frequency components corresponding to torsional mode oscillations of a rotating system that comprises the rotor of the synchronous generator and a rotating part of an engine or another prime mover. Thus, an adverse phenomenon where the voltage control loop maintains or even amplifies the torsional mode oscillations can be avoided.

摘要： A control system for an internal combustion engine comprises a primary controller (301), which compares a feedback value to a setpoint value and produces a primary output. The feedback value is an indicator of a measured dynamic quantity in a process (101) in said internal combustion engine. A secondary controller (302) receives an input value and produces a secondary output according to a transfer function. The input value is an indicator of a measurable disturbance affecting the process (101). A combiner (303) receives said primary and secondary outputs and delivers their combination as a control signal to an actuator (104). The secondary controller (302) receives said primary output or a derivative thereof, and adapts said transfer function based at least partly on an aim of maintaining said primary output at a fixed value.

摘要： The aim of the invention is to use a separate device (11) between the analog (8) and digital (6) communications lines to convert the digital load sharing information from the digital communication line (6) to the analog communication line (8) and vice versa. The device (11) does not generate power itself for the load sharing and therefore does not disturb the load sharing of the generators (5,7) on the both sides of the device (11). The device (11) can be seen as a gate between the digital communication line (6)and the analog communication line (8). The device(ll) simulates load situation of the generator/s (5) connected to the digital communication line (6) for load sharing with other generator/s (7) connected to the analog communication line (8), and similarly it simulates load situation of the other generator/s (7) connected to the analog communication line (8) for load sharing with the generator/s (5) connected to the digital communication line (6).
摘要翻译：本发明的目的是在模拟（8）和数字（6）通信线路之间使用单独的设备（11）来将数字负载共享信息从数字通信线路（6）转换成模拟通信线路（8）反之亦然。设备（11）不会为负载共享而产生电力本身，因此不会干扰设备（11）两侧的发电机（5,7）的负载共享。设备（11）可以被看作是数字通信线路（6）和模拟通信线路（8）之间的门极。设备（11）模拟连接到数字通信线路（6）的发电机（5）的负载情况，用于与连接到模拟通信线路（8）的其他发电机（7）进行负载共享，并且类似地，它模拟连接到模拟通信线路（8）的另一个发生器（7）的负载情况用于与连接到数字通信线路（6）的发电机（5）的负载共享。
