    In this paper, control of 2 DOF Helicopter (TRMS System) Based on Gain-Adaptive PID using two methods the approach from the theory of Lyapunov and fuzzy-PID. In particular, the PID controller with fixed parameters may fail to provide acceptable control performance. To improve the PID control effect, new designs of the Lyapunov gain Scheduled PID controller and fuzzy-PID were presented in this paper. The proposed techniques were applied to the TRMS, The parameters of PID controller were adjusted by an adaptation algorithm gradient type, used to tune in real-time the controller gain, the proposed adaptive PID controllers were compared with the conventional PID. The obtained results confirm the effectiveness of the proposed method.

    Gain-Adaptive PID-fuzzy MPPT for PV System
    (university Of Eloued جامعة الوادي, 2020-02-23) Boudia assam; Messalti sabir; Harrag abdelghani
    In this paper, in this paper, new improved maximum power point tracking based on Gain-Adaptive PID has been designed and studied using PID-fuzzy approach. PID controller is the most widely adopted method in industry due to many reason (simplicity, low cost), however, it’s not perfect suitable for systems, fuzzy logic is used to enhance PID controller by adapting the PID parameters. This paper present PID-fuzzy as maximum power point tracking (MPPT) for photovoltaic system to maximize photovoltaic outputs (voltage, power and current).
