【Abstract】 This paper presents a computer-aided analysis for robust-ness of control systems through an illustrative control system with high resistibility todisturbances. The proposed analysis method can easily determine the effect of system parameter perturbations on its stability and dynamic behaviour, and find out the stable parameter regions. It can also overcome certain difficulties in theoretical analysis and avoid the error caused by the linearization approximation. This method, together with CAD, will be useful for the design and adjustment of industrial control systems.更多还原
