Application of intelligent PID controller of zero-pole placement in control system

To resolve the PID control problem of unknown systems, intelligent PID controller of zero-pole placement was designed according to PID control system theory and zero-pole placement theory. This controller has simple structure and good practicability. Its order is only related to the order of controlled system's denominator, and has no relationship to the numerator's order. It is possible to use a low-order controller to control the actual higher-order system. Its robustness and adaptive character were well proved through lots of simulations and experiments.
