Proportional gain (P) Proportional gain is used for all tuning situations. It introduces a
control factor that is proportional to the error signal. Proportional gain
increases system response by boosting the effect of the error signal on
the servovalve.
Keep in mind:
• As proportional gain increases, the error decreases and the
feedback signal tracks the command signal more closely.
• Higher gain settings increase the speed of the system response.
• Too much proportional gain can cause the system to become
unstable.
• Too little proportional gain can cause the system to become
sluggish.
• Gain settings for different control modes may vary greatly. For
example, the gain for force may be as low as 1 while the gain for
strain may be as high as 10,000.
Note The rule of thumb is—adjust gain as high as it will go without going
unstable.
