在以下测试过程中，AVR或FCR操作模式的响应可以通过在电压设定点中产生阶跃变化来确定。增加和减少电压设定值会产生阶跃变化。设定值的典型变化在1%和10%之间。观察产生的发电机响应。

观察电压过冲和稳定时间，并调整以下增益设置以获得所需性能。典型的测试是在额定电压下运行发电机。

使用图表记录器（或合适的电压记录设备）监测发电机的输出电压，启动设置更改。如果观察到的瞬态响应过冲过多，则减小Kp值。如果过冲很小并且响应太慢，则增加Kp值。增加Ki值会减少达到稳定状态所需的时间。

为了改善阶跃变化的瞬态响应，增加Kd。如果稳态输出中存在过多抖动，则减小Kd。由于所有这些项都会影响特性响应，因此有必要平衡这三个项以获得所需的发电机响应。

During the following test, the response of the AVR or FCR operating mode can be determined by generating a step change in the voltage setting point. Increasing and decreasing voltage setpoints produce step changes. The typical change in setpoint value is between 1% and 10%. Observe the resulting generator response.

Observe the voltage overshoot and stability time, and adjust the following gain Settings to get the desired performance. A typical test is to run the generator at rated voltage.

Use a chart recorder (or suitable voltage recording device) to monitor the generator's output voltage and start setting changes. If too much transient response overshoot is observed, the Kp value is reduced. If the overshoot is small and the response is too slow, increase the Kp value. Increasing the Ki value reduces the time required to reach a steady state.

In order to improve the transient response of step change, Kd is increased. If there is too much jitter in the steady-state output, reduce the Kd. Since all of these terms affect the characteristic response, it is necessary to balance these three terms to obtain the desired generator response.
