An improved swarm intelligence algorithms-based nonlinear fractional order-PID controller for a trajectory tracking of underwater vehicles
This paper presents a nonlinear fractional order proportional integral
derivative (NL-FOPID) for autonomous underwater vehicle (AUV) to solve the path tracking problem under the unknown disturbances (model uncertainty or external disturbances). The…

Hybrid clustering based on multi-criteria segmentation for higher education marketing
Market segmentation in higher education institutions is still rarely applied
although it can assist in defining the right strategies and actions for the
targeted market. The problem that often arises in market segmentation is how
to exploit the…

High frequency signal injection method for sensorless permanent magnet synchronous motor drives
The objective of this project is to design a high frequency signal injection
method for sensorless control of permanent magnet synchronous motor
(PMSM) drives. Generally, the PMSM drives control requires the appearance of speed and positon sensor…

A novel two-polynomial criteria for higher-order systems stability boundaries detection and control
There are many methods for identifying the stability of complex dynamic
systems. Routh and Hurwitz’s criterion is one of the earliest and commonly used analytical tools analysing the stability of dynamic systems. However, it requires tedious and…

Comparative and analysis of evaluation of several direction of arrival estimation methods
Modern-day, global, and clever array systems have several distinguished
approaches with regard to a wireless device. In this paper, a comparative
analysis has been carried out amongst nine direction of arrival (DOA)
algorithms: Capon, multiple…
