Multiple-input single-output current-mode universal filter using translinear current conveyors

  This paper presents a new current-controlled current-mode universal filter with multiple inputs and single output employing one translinear current conveyor (CCCII), one CCCII with controlled current gain and two grounded capacitors. The employment of grounded capacitors makes the circuit ideal for integration. The proposed circuit can provide low-pass, band-pass, high-pass, band-stop and all-pass current...

Designing the intelligent controller for photovoltaic system in islanding mode operation

  In this paper, an optimal controller is proposed to control the voltage of photovoltaic system as distributed generation (DG) using intelligent algorithm in islanding mode operation. The control algorithm used in the studied control plant during load variations is based on the reinforcement learning (RL) algorithm. To control the examined plant, this algorithm has tried to prevent controller output...
