The study shows that under certain conditions the permanent magnet synchronous motor drive system (PMSM) is displays chaotic oscillation. In this paper, stabilization problems of the PMSM chaotic system is investigated. For this reason, state dependent riccati equation (SDRE) is used. This method was applied to chaotic system in three ways. Numerical simulation will show that this method much better, faster, more effective than previous methods can be PMSM chaotic system mode to bring stability.
