Stabilization and Hybrid PID Control for One-order Unstable System with Time Delay

For one order non-minimum phase system with time delay, a hybrid PD control method is introduced. The tuning formulas and modified scheme for the control parameters are inferred. The characteristics of controlled system, such as indetermination and slow time-variety, are taken into account. The P11) controller constructed by neural network is used to online adjust the parameters of P11) control. It widens the P11) controller application scope. The simulating result of the close-loop system is good. The parameter tuning is simple and good control performances are obtained.
