Finite Element Analysis of Seepage through an Earthen Dam by using Geo-Slope (SEEP/W) software
In this research work, finite element approach is employed to solve the governing differential equations pertaining to seepage through body of dam its foundation. For this purpose, the foremost focal point is discretization of domain into finite elements by placement of imaginary nodal points and discretization of governing equations into a system of equations; an equation for each nodal point or element and solving it for the unknown variables.
This paper addresses an initial study of a modelfree PID tuning based on simultaneous perturbation stochastic approximation (SPSA) for liquid slosh control. The SPSA method is used to optimize the PID parameters such that the liquid slosh is minimized. In order to validate our model-free design, a liquid slosh model is considered to represent the lateral slosh motion. The simulation results demonstrate that the proposed model-free method has a good potential in reducing the liquid slosh without explicitly modeling the liquid slosh behavior.
