The research on it can be representative of that on a nonlinear, multivariable, absolute unstable system. The method and thought for controlling it is very useful to the control theory and process control. It can check control theories and methods effectively. IPS is an inte- gration of mechanical and electrical systems, which the mechanical part of Newton's mechanics to follow the law, the Department of Electrical Electromagnetic follow the basic theorem. Therefore, we may first obtain the more accurate mathematical modeling through the mechanism modeling method to carry on the simulation to it, gains the system model parameter through the experimental survey. The experiment use the feedback principle, compare with the output in the reference quantity, and the deviation of them as a means of control. Based on pole-placement, the pole will deploy an expectative point, making the leading closed-loop system nodes have the desired damping ratio and non-damping natural frequency. This experiment use the Matlab obtained a system designed by the state feedback gain matrix, stands upside IPS on the modeling and simulation by Simulink. Labview selected as a feedback control system interface design and development tools, carries out IPS various program function.
