摘要: The aim of this paper is to present analytic tuning rules which are as simple possible and still result in a good closed-loop behavior. starting point has been the IMC PID Rivera, Morari Skogestad (1986) have achieved widespread industrial acceptance. integral term modified improve disturbance rejection for integrating processes. Furthermore, rather than deriving separate each transfer function model, we start by approximating process first-order plus delay processes (e.g. using “half method”), then use single rule. This much simpler appears give controller tunings with comparable performance.
