Yayın A gain-switched self-optimizer for braking controller(John Wiley and Sons Ltd, 2017-06) Dinçmen, ErkinAn emergency braking controller is developed with improved operation characteristics near the maximum friction zone. The methodology is based on self-seeking a-priori unknown optimum operation point to maximize a performance function representing the optimal behavior of the considered dynamic system. Sliding mode with uncertain direction of control vector approach is utilized in the algorithm. An adaptive variable gain is utilized in the algorithm to improve its performance. Via the variable gain, both fast convergence to the a-priori unknown optimum operation point and reduced magnitude of oscillations in the braking moment inputs resulting less aggressive control action are achieved.Yayın Design of voltage-mode and current-mode PID controllers using a single Add-Differentiate IC (AD-IC)(Birkhauser, 2025-12-22) Minayi, Elham; Göknar, İzzet CemIn this paper, voltage and current mode proportional–integral–derivative (PID) controller circuits are presented in one topology, utilizing only a single active component, Add-Differentiate Integrated Circuit (AD-IC) along with two passive resistors and two passive capacitors. The effectiveness and performance of the proposed circuits are validated through sensitivity, non-ideality analyses and PSPICE and MatLab simulations.
