ملخص

Thispaper presents a new nonlinear controller design method for regional pole placement of uncertain discretetime systems. The constraint of control input saturation is considered in the design. A sufficient condition is derived for the robust stabilization and the desireddynamic performance represented by the settling time and damping ratio.The design is formulated in terms of linear matrix inequality (LMI) optimization. The effectiveness of the proposed design isillustrated by two examples. The first one ishard disk drives, whoseuncertainty is modeled bya norm-bounded form. The resulting controller does not violate the limits, and the second example is on regional pole placement for an uncertain system with and without control saturation. Application to vehicle active suspension to achieve comfortable dynamic performance by pole placement and avoiding actuator saturation is also considered. The results are compared with passive suspension system.
