The overshoot and equilibration of saltation
WebbThe overshoot using sliding mode control is 8.5%, and the overshoot of particle swarm sliding mode-fuzzy PID is 6.7%. The step length of the test results of the two controllers is 2 mm. Compared with these two control systems, the magnetic levitation motion control system proposed in this paper has better system performance by optimizing the … Webb1 jan. 2000 · Equilibration of saltation Equilibration of saltation Spies, Peter‐Jost; McEwan, Ian K. 2000-01-01 00:00:00 A two‐dimensional numerical model of the saltation process …
