These controllers are meet requirements GB Security Quality Supply Standard (GB-SQSS), which ...

This article suggests the control of current and speed approach to reduce torque ripple in BLDC motor. Initially, renewable energy hybrid power system (REHPS) is composed a generation PV, fuel cell (FC), storage battery bank. REHPS uses solar as their main source electricity during day. It secondary for maintenance at night or periods shaded conditions. The novelty proposed method achieve minim...

A design of an optimal backstepping fractional order proportional integral derivative (FOPID) controller for handling the trajectory tracking problem wheeled mobile robots (WMR) is examined in this study. Tuning parameters a challenging task, to overcome issue hybrid meta-heuristic optimization algorithm has been utilized. This evolutionary technique known as whale grey wolf optimizer (HWGO), w...

in this paper, we apply the local fractional adomian decomposition and variational iteration methods to obtain the analytic approximate solutions of fredholm integral equations of the second kind within local fractional derivative operators. the iteration procedure is based on local fractional derivative. the obtained results reveal that the proposed methods are very efficient and simple tools ...

A novel fractional order (FO) fuzzy Proportional-Integral-Derivative (PID) controller has been proposed in this paper which works on the closed loop error and its fractional derivative as the input and has a fractional integrator in its output. The fractional order differ-integrations in the proposed fuzzy logic controller (FLC) are kept as design variables along with the input-output scaling f...

This paper deals with the design, implementation and analysis of an integer order (IO) and fractional order (FO) based Proportional Integral Derivative (PID) controller, for speed regulation in a chopper fed Direct Current (DC) motor drive. The interdependent parameters of PID and FOPID controllers are designed in both time and frequency domain. In both domains, designs of controllers are formu...

Supply-demand-based optimization (SDO) is a swarm-based optimizer. However, it suffers from several drawbacks, such as lack of solution diversity and low convergence accuracy search efficiency. To overcome them, an effective supply-demand-based (ESDO) proposed in this study. First, enhanced fitness-distance balance (EFDB) the Levy flight are introduced into original version to avoid premature i...
