    • In conventional polar-loop transmitter circuits, using two feedback circuits intended to control the amplitude in an open loop and phase of a power output in closed loop, respectively, during transmission, causes current consumption to increase during delivery of a small power output. Therefore, a complex table has to be prepared in order to correct the nonlinearities in the amplitude-to-amplitude characteristic of the power amplifier and the amplitude-to-phase characteristic thereof. In order to reduce the current consumption required for the delivery of a moderate or small power output, a polar-loop transmitter circuit in which two feedback circuits intended to control the amplitude and phase of the power output respectively are active when the power amplifier delivers a large power output exhibiting strong nonlinearity, and when the power amplifier delivers a moderate or small power output, the amplitude of the power output is controlled in the open loop.
    • 在常规的极性环路发射机电路中,在传输期间,分别使用两个反馈电路来分别控制开环中的幅度和闭环中的功率输出的相位,从而在输出小功率输出期间使电流消耗增加。 因此,为了校正功率放大器的幅度 - 幅度特性的非线性及其幅相特性,必须准备复杂的表格。 为了降低传递中等或较小功率输出所需的电流消耗,一个极环回路发射器电路,其中分别用于控制功率输出的幅度和相位的两个反馈电路在功率放大器输出 大功率输出显示强非线性,当功率放大器输出中等或较小的功率输出时,功率输出的幅度在开环中被控制。

    • In a heating apparatus for heating the air sucked into a gas turbine by a heat exchanger, the temperature fluctuation of the heated air is suppressed even in the period, for which a steam source to be fed to the heat exchanger is changed. For that suppression, a heat exchanger (30) is fed with both a self-can steam (S1), the feed rate of which is controlled by a self-can steam control valve (41), and the auxiliary-steam (S2), the feed rate of which is controlled by an auxiliary-steam control valve (51). At the starting time, the quantity of the auxiliary-steam (S2) is reduced at a constant rate, and the quantity of the self-can steam (S1) is increased while a feedback control and a feedforward control are being made. At the stopping time, the quantity of the self-can steam (S1) is reduced at a constant rate, and the quantity of the auxiliary-steam (S2) is increased while the feedback control and the feedforward control are being made.
