“…Proportional-integral-derivative (PID) controller has widely been used in process control industries due to its simple structure, robust performance and ease in implementation in practice [1][2][3]. The basic idea of PID controller is depended on the tuning of controller parameters controller gain K c , integral time τ I and τ D , sometimes with filter time constant τ f in order to obtain the accuracy and performance of controllers.…”

Abstract. This paper presents a new control strategy which unifies the direct and indirect multi-scale control schemes via a double-loop control structure. This unified control strategy is proposed for controlling a class of highly nonminimum-phase processes having both integrating and unstable modes. This type of systems is often encountered in fed-batch fermentation processes which are very difficult to stabilize via most of the existing well-established control strategies. A systematic design procedure is provided where its applicability is demonstrated via a numerical example.

“…Chen et al [16] investigated the calculation of set point weighting PID parameter for unstable first-order time-delay systems. In [18], the internal model controller equivalent PID tuning rules are synthesized for a low order unstable delay systems in [18]. In [19], the authors presented an adaptive iterative learning control scheme for a class of strict-feedback nonlinear time-delay systems with unknown nonlinearly parameterised and time-varying disturbed functions of known periods.…”

Abstract:In this paper, the problem of stabilizing an unstable second order delay system using classical proportional-integralderivative (PID) controller is considered. An extension of the Hermite-Biehler theorem, which is applicable to quasi-polynomials, is used to seek the set of complete stabilizing proportional-integral/proportional-integral-derivative (PI/PID) parameters. The range of admissible proportional gains is determined in closed form. For each proportional gain, the stabilizing set in the space of the integral and derivative gains is shown to be a triangle.

In industrial processes, unstable system produces undesirable peak overshoot. So, PID controller with compensator and set point filter is designed using direct synthesis method. The set point filter reduces the peak overshoot. PID controller with compensator improves the overall response of the system. In this method, the characteristics equation of the system with PID controller and a compensator is compared with a desired characteristics equation. A single tuning parameter is used to find controller parameters, compensator and set point filter.
