Abstract:
Solution of a problem for tolerance analysis of electrical circuits with a probabilistic statement is presented. The problem parameters vary independently according to a normal distribution law, while the output is a scalar value. The original tolerance problem leads to two equivalent global optimization problems with constraints. Every optimization problem is extended by an inequality constraint describing the so-called hyper-ellipse of equal probability. Since the optimization model is practically impossible to solve by a global algorithm, an approach based on a local algorithm is used. The initial point for the latter is determined analytically after the worst-ease (WC) solution is fbund. The approach is compared to the traditional Monte Carlo OvIC) simulation through an illustrative numerical example.
