“…The graphic tuning methods attempted to find the centroids of stability regions in the controller parameter space, considering a point which is situated away from the boundaries of the stability region, and consequently the controller, which is tuned based on such a point, will be nonfragile [17], in other word, robustness. The stability regions in the controller parameter space based on two parameters model and FODT model are detailed in [18] [19], respectively.…”

In the paper recent design and tuning methods of PID controllers are summarized briefly. Several decades have seen the widely application of PID controllers and the design and tuning methods have been of considerable development. Process model identification, PID controller structure design, PID parameters tuning methods and the use and expansions of PID are described in turn. PID parameter tuning methods are highlighted.

Auto throttle controls directly the speed of the car. The driver can trample accurately and smoothly trample accelerator pedal to control the speed. In order to make the driver can real-time track the set the speed in the process of vehicle driving, a method based on Ziegler Nicholsfrequency response of the adaptive PID controller is proposed. The control circuit identifies online important critical frequency response characteristics of process object through input and output data in the process normal operation, and then the system online update PID controller parameters based on Ziegler-Nichols setting rules or by the improved method. The method can smoothly, rapidly and accurately control the throttle mechanical leg, and make driving robots has good speed tracking precision during the automatic driving of vehicle. The method has good stability and robustness.

“…Three-dimensional stability spaces for PID controller design are proposed in (Bahavarnia & Tavazoei, 2013), enabling new results to be achieved through ZN theory. The so-called advanced adjustment for PID controller design with ZN theory is addressed in (Rodríguez, Han, Keel, & Bhattacharyya, 2017), relating the gain margin and phase margin specifications to the performance of curves projected through ZN theory to simultaneously achieve a controller design with the desired margin specifications.…”
