In this paper a new PID controller is presented. Its peculiarity consists in the non integer order of the derivative and integral, being this order variable in the range [0,1], and providing two further parameters to the controller. The key element is a Multi-layer Perceptron that evaluate a non integer order integration. The neural network approach allows to overcome some problems related to p...

By using the particle swarm optimization (PSO) algorithm, a novel design method for the self-tuning PID control in a slider–crank mechanism system is presented in this paper. This paper demonstrates, in detail, how to employ the PSO so as to search efficiently for the optimal PID controller parameters within a mechanism system. The proposed approach has superior features, including: easy implem...

This paper deals with the design of a fuzzy PID Controller (FPIDC) with dynamic gain through a fuzzy scheme. The gain factor of Proportional, Integral and Derivative is varied according to process of the proposed dead time. FPIDC is modified which depends on the normalized change of error of the controlled variable (ec) and its number of fuzzy partitions. The proposed scheme is tested for a wid...

An unsolved ancient problem in position control of robot manipulators is to find a stability analysis that proves global asymptotic stability of the classical PID control in closed loop with robot manipulators. The practical evidence suggests that in fact the classical PID in industrial robots is a global regulator. The main goal of the present paper is theoreticall...

In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...

The Photovoltaic (PV) system is an eco-friendly renewable energy that integrated with a DC-DC buck-boost converter to generate electrical as per the variations in solar irradiance and outdoor temperature. This article proposes novel Adaptive Fractional Order PID (A-FOPID) compensator self-adjusting fractional orders extract maximum power from stand-alone PV ambient conditions change. reference ...
