An increase in gain in most systems, leads to

### Right Answer is:

Smaller damping ratio

#### SOLUTION

**The damping ratio is inversely proportional to the gain, therefore, the larger proportion of the gain results in a faster response and a smaller steady-state error.****With the increase in gain damping ratio decreases and the damped frequency increases.**- The overshoot increases with an increase in the gain while delay time and rise time of the system is reduced hence the system response faster.

**Effect of controller parameters on system performance**
