Based on the explained and proved theorems, this paper presents a new robust QFT controller design for uncertain multivariable linear systems with hard time-domain constraints on their output signals, as well as constraints on their bandwidth. In this method, the multivariable process is converted to a new process using an internal feedback and diagonal controller. With the aid of basically non-interacting(BNI) method in QFT, the resulting process is devided into several SISO systems and proper controllers is then designed by QFT. Controller transfer function matrix is diagonal, therefore, desired bandwidth can be acquired. Finally a comparison of the proposed method and the conventional QFT method, as well as its application, is shown in an example.
