Tuning Three-Term Controllers for Integrating Processes with both Inverse Response and Dead Time
Most industrial processes respond to the actions of a feedback controller by moving the process variable in the same direction as the control effort. However, there are some interesting exceptions where the process variable first drops, then rises after an increase in the control effort. This peculiar behaviour that is well known as “inverse response”, is due to the non-minimum phase zeros appe...
متن کاملSimple Tuning Rules of PID Controllers for Integrator/Dead time Processes
In this paper, simple rules for tuning PID controllers for integrator/dead time processes are proposed. These rules are derived by the optimization of a discrete-time error integral criterion called the switch time weighted summation of squared error (SWSSE) criterion. In this criterion, the first M samples of the transient response are weighted by 1, while the remaining samples until the end o...
متن کاملNew tuning rules for PI and fractional PI controllers
This paper presents new tuning rules for PI and fractional PI control of processes that are typically found in process control. The rules are based on characterization of process dynamics by three parameters that can be obtained from a simple step response experiment. The rules are obtained by minimizing a frequency objective function subject to a constraint on the maximum sensitivity. Comparis...
متن کاملZiegler-nichols Type Tuning Rules for Fractional Pid Controllers
This paper presents two sets of tuning rules for fractional PIDs that rely solely on the same plant time-response data used by the first Ziegler-Nichols tuning rule for (usual, integer) PIDs. Thus no model for the plant to control is needed; only an Sshaped step response is. These rules are quadratic and their results compare well with those obtained with rule-tuned integer PIDs. INTRODUCTION C...
متن کاملLocally optimal controllers and globally inverse optimal controllers
In this paper we consider the problem of global asymptotic stabilization with prescribed local behavior. We show that this problem can be formulated in terms of control Lyapunov functions. Moreover, we show that if the local control law has been synthesized employing a LQ approach, then the associated Lyapunov function can be seen as the value function of an optimal problem with some specific l...
