If the changes listed below ate made separately, determine whether the system becomes more stable, less stable, or remains the same. Try to use the Bode stability criterion and sketches of frequency response graphs to solve this problem. 1. Controller gain increases. 2. Length of pipe between measuring element and tank increases. 3. Measuring element is inserted in tank. 4 Integral action is provided in controller. 5. A larger valve is used (i.e., one with a higher C, value). 17.9. For each control system shown in Fig. P17.9, determine the characteristic equation of the closed-loop response and determine the value of K c that will cause the system to be on the verge of instability (i.e., find the ultimate gain, K,,). If possible, use the Routh test. Note that the feedback element for System B is an approximation to e-2s.
