P Control Third Order Type 0 Step response and Bode Plot

Cuthbert Nyack
Both applets show the step response and root locus for a type 0 third order system with P control. The continuous system can be unstable. The sampled system is obtained by a ZOH and Gs(s).
eg parameters (K, 0.5, 1.0, 1.5, 0.05, 1.4). The Sampled system is stable for K < 7.0 and the continuous system is stable for K < 7.7.
eg parameters (K, 0.5, 1.0, 1.5, 0.2, 2.4). The Sampled system is stable for K < 5.9 and the continuous system is stable for K < 7.7.
eg parameters (K, 0.5, 1.0, 1.5, 0.5, 4.4). The Sampled system is stable for K < 4.5 and the continuous system is stable for K < 7.7.
