ASSESSMENT OF PID-BASED CONTROL OF SERVOACTUATORS FOR FLIGHT REGULATION OF SMALL UNMANNED AERIAL VEHICLES

Mahmud S. Zango, Ameer Mohammed^*, Jamilu U. Yahaya, Khalid K Dandago, Muhammad I Muhammad, Abdulbasit Hassan

Flight control systems for unmanned aerial vehicles (UAVs) are responsible for maintaining safe flight – they are required to be reliable and robust. Flight regulation is achieved by controlling servomotors linked to flight control surfaces – ailerons, rudder, elevators and flaps. The most important parameters in servomotor control are position and speed. Hence, this work performed an assessment o...

REVIEW ON METAHEURISTIC-BASED DECISION TREE INDUCTION

Ismaila Mahmud^*, Abubakar Abdulkarim, Sulaiman Haruna Sulaiman, Umar Musa

Decision tree is one of the well-known machine learning algorithms which remain popular due its simple implementation and ease of understanding. Existing techniques used in inducing decision tree have shown that they suffer data overfitting which leads to producing small size of decision tree model. To address the drawback and improve the performance of the algorithm, hybridization of metaheuristi...

DESIGN AND IMPLEMENTATION OF A HANDWRITING TEXT RECOGNITION SYSTEM

A. Musa^*

Handwritten characters are difficult to recognize due to diversity of human handwriting style, variation in angle, size and shape of letters. In this work, an extensively employed method of handwritten text recognition is used to transform handwritten data into electronic format or digital form, preprocess, extract distinctive features, and classify written characters. The proposed approach is to ...

A SIMPLIFIED METHOD FOR CONVERSION OF PUMP TO TURBINE (PAT) FOR RURAL AREAS APPLICATION

S. M. Lawan^*, W. A. W. Z. Abidin, B. Abdullahi, F. A. Umar, A. Aminu

Electricity plays an important role in our daily life. Thus, the generation of electricity becomes a first priority issue. Electricity that generates from non-renewable energy such as coal or diesel is a common method for decades. More research had done on renewable energy such as hydro, wind, and biomass in order to produce green energy. For example, hydro turbine utilizes water to revolve the sh...

DEVELOPMENT OF AN OPTIMIZED DUAL RELAY SETTING COORDINATION SCHEME FOR DISTRIBUTION NETWORK WITH DISTRIBUTED GENERATION

Babatunde Lambo^*, Y. Jibril, Boyi Jimoh, Adamu S. Abubakar

In Distributed Generation systems (DG), the fault current through a relay in forward direction is mostly higher than in the reverse direction. Thus, it is desirable to have dual setting directional over current relay (DOCR) which can operate for both forward and reverse direction of fault current with two independent relay settings. The presence of DGs gives additional fault current contribution t...
