Output Tracking of Non-minimum Phase Nonlinear Systems Through Exact Linearization
نویسنده
چکیده
In this paper, we develop a method to design the input control to track the output of a nonminimum-phase nonlinear systems asymptotically. The design of the control inputs is based on an exact linearization. To perform the exact linearization, the other output should be selected such that its relative degree is equal to the dimension of the system. Furthermore, the desired output of the output which has been selected will be set based on the desired output of the original system. In applying the input control which is obtained via output-input linearization sometimes led to singularity. To overcome this singularity problem, polynomial control is developed around the point of singularity.
