    A Model Identification Method for Tuning of PID Controller in a Smith Predicator Structure
    (Elsevier Science Bv, 2016) Deniz, F. Nur; Tan, Nusret
    In this paper, a model identification method is presented for tuning of PID parameters in Smith predictor structure based on internal model control. The purposed method fits stability boundary locus (SBL) of a plant model with SBL of a FOPDT (First Order Plus Dead Time) or a SOPDT (Second Order Plus Dead Time) model to determine the controller parameters. Two examples are employed to illustrate the applicability and simplicity of the purposed method in both tuning of controller parameters and identification of model parameters for an integer order plant and a fractional order plant.

    Tuning of Fractional Order PID Controllers Based on Integral Performance Criteria Using Fourier Series Method
    (Elsevier, 2017) Deniz, F. Nur; Yuce, Ali; Tan, Nusret; Atherton, Derek P.
    This paper presents a time domain tuning technique for a fractional order PID controller based on optimizing an integral performance criterion. A Fourier series based method (FSM) is used to calculate accurately the step response of the closed loop control systems so as to determine the exact value of the error function performance criterion. The initial guesses for the FOPID controller parameters to be optimized are found using the analytical solution for integral squared error optimization for an integer order PID controller. The proposed method is used for two test plant transfer functions by comparing different optimal FOPID controllers. The results show that the design technique based on optimization of different integral performance criteria give good step responses for FOPID controller.
