At the same time , it gave frequency domain and time domain solutions of system equations about two motions on pure rolling and rolling coupled swaying of the ship . based on analyzing the control principle of the anti - rolling tank , the optimal control of controlled passive tank is devised according to the principle of optimal control , and the implementation approach presented . the author also studies the controller design of the activated tank , presents the technique of enumerating tank active force , and simulates the three kinds of tank system 在分析减摇水舱控制机理的基础上,根据最优控制原理,提出了可控被动式减摇水舱的最佳控制,给出了最佳控制的实现方法;研究了主动式减摇水舱控制器的设计及确定水舱主动力的方法;对被动式、可控被动式和主动式减摇水舱系统进行了仿真分析。
The comparison between the results of calculation and measurement shows that the two results are in good agreement for the broad band antenna in the l band and the waveguide - coax converter of bj48 type used as antenna in the c band , with a difference of less than 0 . 7db , and that the two results also agrees well in the x band for the waveguide - coax converter of bj100 type used as antenna , with an error close to 1db only at few points in the given frequency range 比对结果表明: l波段(加脊天线) 、 c波段( bj48型波导同轴转换作为接收喇叭)的模拟结果与实测结果符合得较好,误差小于0 . 7db ;在带内, x波段( bj100型波导同轴转换作为接收喇叭)的模拟结果与实测结果比较一致,只在个别频率点处误差近1db 。
But at present variable frequency control sets mainly the given frequency on the ground of the status of oil well , and makes the beam unit extract oil by the given frequency . consequently , the output feature of motor is still hard , and ca n ' t adjust the output torque of motor according to the load feature of beam unit 但是,目前抽油机变频控制主要还是根据油井状况来设定给定频率,使抽油机电机按给定频率来抽油,电机的输出特性比较硬,而且还不能根据抽油机的负载特性来调节电机的输出转矩,有时还存在着发电状态等问题。
In the circumstances of the te11 mode mixed with the given parasite modes , the errors from the practically used directivity can be corrected with the calculated difference between dh and d . the effective area of the receiving antenna is calculated with the established models , and measured at some points in the given frequency range 在已知混入te11模式中杂模成份及其比例的情况下,可以通过计算出dh与d的差值,对采用的方向性系数进行误差修正。通过建立相应模型,对接收喇叭的有效面积进行了计算,并在部分频率点上进行了实测。
