Standard numerical optimization approaches require several restrictions. So do exact optimization methods such as the Linear Programming approach appeal for linearity and Nelder-Mead for unimodality of the loss function. One method to relax these assumptions is the Simulated Annealing approach, which reduces the risk of getting trapped in a local optimum. However, the standard implementation st...

This paper describes a robust and non-fragile H∞ controller design method for descriptor systems with parameter uncertainties and time delay, as well as a static state feedback controller with multiplicative uncertainty. The controller existence condition, as well as its design method, and the measure of non-fragility in the controller are proposed using linear matrix inequality (LMI) technique...
