Process Control and Instrumentation Suppose that the gain, time constant and dead time of a process with the following transfer function:Gc(s) = 10 exp( - 0.1s)/(0.5s + 1) are known with a possible error of ± 20% of their values. The largest permissible gain Kc of a proportional controller needs to be calculated below taking the values of process gain, time constant and dead time as 12, 0.6, 0.12 8, 0.6, 0.12 12, 0.4, 0.08 8, 0.6, 0.08 12, 0.6, 0.12 8, 0.6, 0.12 12, 0.4, 0.08 8, 0.6, 0.08 ANSWER DOWNLOAD EXAMIANS APP
