LMI for Max Percent Overshoot Poles The following LMI allows for the verification that poles of a system will within a maximum percent overshoot constraint. This can also be used to place poles for max percent overshoot when the system matrix includes a controller, such as in the form A+BK. The System We consider the following system: or the matrix , which is the state matrix. The Data The data required is the matrix A and the max percent overshoot you wish to verify. The Optimization Problem To begin, the constraint of the pole locations is as follows: , where z is a complex pole of A. The goal of the optimization is to find a valid P > 0 such that the following LMI is satisfied. The LMI: LMI for Max Percent Overshoot Poles The LMI problem is to find a matrix P satisfying: Conclusion: If the LMI is found to be feasible, then the pole locations of A, represented as z, will meet the max percent overshoot specification of , and the poles of A satisfy the previously defined constraint.
