The DC motor is perhaps the most widely used industrial energy converter whose performance decrease over time. In this work, an experimental data is used to create a mathematical model of the DC motor for performance analysis. Using state space analysis and Matlab, information on the internal behaviour of the DC motor are obtained and based on the design specification; a controller is designed to improve the performance.

Anticipating short/long-term consequences, this study hypothesised the effects of LULC variables in Akure, a developing tropical rainforest city in south-west Nigeria. A differentiated trend of urban LULC was determined over a period covering 1999–2019. The study showed the net change for bare land, built-up area, cultivated land, forest cover and grassland over the two decades to be −292.68 km2, +325.79 km2, +88.65 km2, +8.62 km2 and −131.38 km2, respectively. With a projected population increase of about 46.85%, the study identified that the built-up land cover increased from 1.98% to 48.61%. The change detection analysis revealed an upsurge in built area class. The expansion indicated a significant inverse correlation with the bare land class (50.97% to 8.66%) and grassland class (36.33% to 17.94%) over the study period. The study ob...
