Performance-based PID tuning and its experimental evaluation

In industrial processes represented by petroleum and refinary processes, it is necessary to establish the performance-driven control strategy in order to improve the productivity, with the control performance id firstly evaluated, and the controller is reconstructed. This paper describes a tunng scheme which are based on the above control mechanism. In calculating the PID parameters, the desired control performance is considered. The behavior of the proposed control scheme is evaluated in air pressure experiment.
