摘要：
This This paper describes a new method for identifying the system parameters of a dynamic system in state-space form by minimizing the least-squares error of the measured system output. The variable projection method is used to eliminate the necessity of estimating the system states, and reduce the system identification cost function to a function of only the system parameters. The method is verified using real data of the angle of a pendulum mounted on a trolley with position control.
