Decomposition Rates Of Introduced C. Sulphureus Vs. Native A. Rhomboidei ​, Jonathan R. Loftis, Todd Hoskinson, Gabi Palumbo, Marven Roufail, Darlene Panvini

Science University Research Symposium (SURS)

Decomposition rates are important in measuring the health of an ecosystem. They can indicate the rate at which nutrients cycle through the habitat. However, not all leaves will decompose at the same rate, which impacts the rate at which nutrients can be recycled. The introduction of non-native species may bring about changes to the native nutrient cycle, as these plants may have a different rate of decomposition than those of native species. This can affect the amount of nutrients available in the soil surrounding native and non-native plant species, which in turn affect other native species. Using two species of …

An Improved Conditional Integrator Sliding Mode Controller Based On Swarm Intelligence For A Magnetic Levitation System, Abdelkader Kerraci, Mohamed Fayçal Khelfi, Zoubir Ahmed-Foitih Nov 2024

An Improved Conditional Integrator Sliding Mode Controller Based On Swarm Intelligence For A Magnetic Levitation System, Abdelkader Kerraci, Mohamed Fayçal Khelfi, Zoubir Ahmed-Foitih

Turkish Journal of Electrical Engineering and Computer Sciences

This paper proposes an enhanced Conditional Integrator Sliding Mode Controller using Particle Swarm Optimization (CISMCPSO) for a magnetic levitation system (MLS). The main advantage of this controller is its robustness to uncertainties and disturbances, which also avoids chattering and ensures zero static steady-state error. The main idea of CISMCPSO is to activate its integral action only when the sliding surface reaches the boundary layer while it is reduced to zero or close to zero elsewhere, which avoids destroying the transient response caused by the conventional integral sliding-mode controller. A particle swarm optimization algorithm schedules the conditional integral term parameter of …
