increasing of word demand load caused a new distributed generation (dg) to enter to powersystem. one of the most renewable energy is the photovoltaic system. it is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.in this paper an optimal pid controller for photovoltaic system systems has been developed. theoptimization techni...

This paper presents a new strategy for digital control and parameters identification of robust fractional order controllers based on fractional reference model. The model consists on an ideal closed-loop system whose open-loop is given by the Bode’s ideal transfer function with the suitable parameters. This technique suggests an online parameters tuning of fractional order PID controller (FPID)...

In this paper a new design method of a self-tuning PID controller is proposed. The PID controller is designed based on generalized predictive control (GPC) including a future reference trajectory. The PID controller given in this paper is based on GPC and, is I-PD type controller. It is shown that the design parameter adjusting the future reference trajectory changes only the integral time of t...

In this paper, a direct synthesis approach to fractional order controller design Is investigated. The proposed algorithm makes use of Taylor series of both desired closed-loop and actual closed-loop transfer function which is truncated to the first five terms. FOPID Controller parameters are synthesized in order to match the closed-loop response of the plant to the desired closed-loop response....

In the context of reaching best way to control movement autonomous cars linearly and angularly, making them more stable balanced on different roads ensuring that they avoid road obstacles, this manuscript chiefly aims reach optimal approach for a fractional-order PID controller (or PIγDρ-controller) instead already classical one used provide smooth automatic parking electrical cars. The PIγDρ-c...

Fractional Calculus is usually applied to control systems by means of the well-known PI?D? scheme, which adopts integral and derivative components non-integer orders ? µ. An alternative approach add equally distributed fractional-order terms PID scheme instead replacing integer-order (Distributed Order PID, DOPID). This work analyzes properties DOPID with five terms, that PII1/2DD1/2 (the half-...

In this paper, a numerical approach for the fractional order proportional-integral-derivative controller (FO-PID) design for the unstable first order time delay system is proposed. The controller design is based on the system time delay. In order to obtain the relation between the controller parameters and the time delay, for several amounts of the plant time delay and the fractional derivative...

The robotic manipulator is considered one of the complex systems that include multi-input, multi-output, non-linearity, and highly coupled. uncertainty in parameters external disturbances have a negative influence on performance system. Therefore, controllers will be designed for these must able to deal with complexities difficulties. Proportional, Integral, Derivative (PID) controller known si...
