We consider a nonlinear control system in finite-dimensional Euclidean space and on finite time interval. The varies over some less interval, the differential equation describing is replaced with other equation. As result, new appears initial study how much integral funnel of changed under such replacement. obtain upper estimate for Hausdorff distance between funnels inclusions related to varie...

Abstract Aiming at the problem of jitter in speed when load changes abruptly during operation a synchronous reluctance motor and poor resistance to disturbance, an integral type sliding film variable structure control algorithm is proposed. The regulation controlled by mode, PI controls current regulation, Simulink simulation model system built, experiments are conducted. results show that, com...

Brain Tumor is an unwanted mass when cells grow abnormally. It puts pressure on certain areas of the brain which dangerously affects its functioning. For severe tumors like malignant, surgery not a good option because they do have definite boundaries and are closely attached with other healthy tissues brain. So chemotherapy preferable in this case to avoid damaging cells. The primary intention ...
