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…

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…

The detection of handguns from live-video in real-time based on deep learning
Many people have been killed indiscriminately by the use of handguns in
different countries. Terrorist acts, online fighting games and mentally
disturbed people are considered the common reasons for these crimes. A real-time handguns detection…
