Which of the following is NOT the disadvantage of lag compensator in a control system?
1. In lag compensator, the attenuation offered by it shifts the gain crossover frequency to a lower point, thereby decreasing the bandwidth.
2. The lag network offers a reduction in bandwidth, and this gives shorter rise time and settling time and so the transient response.
3. A lag compensator somewhat acts as a proportional plus integral controller, hence adversely affects the stability of the system.
4. Though the system response is longer due to decreased bandwidth, the response is quite slow
