Comparison of PIM and the Variational Iteration Methods (VIM) for Solving Linear Optimal Control Problems

Comparison of PIM and the Variational Iteration Methods (VIM) for Solving Linear Optimal Control Problems

Comparison of PIM and the Variational Iteration Methods (VIM) for Solving Linear Optimal Control Problems

This article presents the Parametric Iteration Method (PIM) for finding optimal control and its corresponding trajectory of linear systems. Without any discretization or transformation, PIM provides a sequence of functions which converges to the exact solution of problem. Our emphasis will be on an auxiliary parameter which directly affects on the rate of convergence. Comparison of PIM and the Variational Iteration Method (VIM) is given to show the preference of PIM over VIM. Numerical results ...

Acid rain and environmental problems

Acid rain is an outcome of air pollution which was first discovered in 1581. Acid rain formation is due to the atmospheric discharge of sulfur and nitrogen oxides which are mainly the outcome of burning the fossil fuels. Acid rain can cause environmental disruptions like; damaging the forests, lakes, groundwater, and soils. The damage caused by acid rain depends on the level of acid deposition and the natural sensitivity of soils and water bodies. There are set of solutions suggested which some ...
