Abstract
In many control design problems it is usually of great interest to have direct control over the closed-loop bandwidth and the transfer function from reference to plant output. The Internal Model Control (IMC) design method for stable plants offers this feature. However, there are some shortcomings, inadequacies and limitations with the IMC design method for both stable and unstable plants which will be exposed in this paper. With the aim of keeping the desired features of the IMC design method, we propose a new H-Infinity control design method which addresses open issues and also can be used for both stable or unstable plants in a coherent framework.
