The permanent magnet synchronous motors (PMSMs) may have chaotic
behaviours for the uncertain values of parameters or under certain
working conditions, which threatens the secure and stable operation
of motor-driven. It is important to study methods of controlling or
suppressing chaos in PMSMs. In this paper, robust stabilities of PMSM
with parameter uncertainties are investigated. After the uncertain
matrices which represent the variable system parameters are
formulated through matrix analysis, a novel asymptotical stability
criterion is established. Some illustrated examples are also given to
show the effectiveness of the obtained results. 相似文献

A permanent magnet synchronous motor (PMSM) may have chaotic behaviours under certain working conditions, especially for uncertain values of parameters, which threatens the security and stability of motor-driven operation. Hence, it is important to study methods of controlling or suppressing chaos in PMSMs. In this paper, the stability of a PMSM with parameter uncertainties is investigated. After uncertain matrices which represent the variable system parameters are formulated through matrix analysis, a novel asymptotical stability criterion is established by employing the method of Lyapunov functions and linear matrix inequality technology. An example is also given to illustrate the effectiveness of our results. 相似文献

Controlling chaos in permanent magnet synchronous motor based on finite-time stability theory 下载免费PDF全文
This paper reports that the performance of permanent magnet synchronous motor (PMSM) degrades due to chaos when its systemic parameters fall into a certain area. To control the undesirable chaos in PMSM, a nonlinear controller, which is simple and easy to be constructed, is presented to achieve finite-time chaos control based on the finite-time stability theory. Computer simulation results show that the proposed controller is very effective. The obtained results may help to maintain the industrial servo driven system’s security operation. 相似文献

In this paper we investigate the chaotic behaviors of the fractional-order permanent magnet synchronous motor(PMSM).The necessary condition for the existence of chaos in the fractional-order PMSM is deduced.And an adaptivefeedback controller is developed based on the stability theory for fractional systems.The presented control scheme,which contains only one single state variable,is simple and flexible,and it is suitable both for design and for implementation in practice.Simulation is carried out to verify that the obtained scheme is efficient and robust against external interference for controlling the fractional-order PMSM system. 相似文献

The performance of synchronous reluctance motor (SynRM) degrades due
to chaos when its systemic parameters fall into a certain area. To
control the undesirable chaos in SynRM, a passive control law is
presented in this paper, which transforms the chaotic SynRM into an
equivalent passive system. It is proved that the equivalent system
can be asymptotically stabilized at the set equilibrium point,
namely, chaos in SynRM can be controlled. Moreover, in order to
eliminate the influence of undeterministic parameters, an adaptive
law is introduced into the designed controller. Computer simulation
results show that the proposed controller is very effective and
robust against the uncertainties in systemic parameters. The present
study may help to maintain the secure operation of industrial servo
drive system. 相似文献

The permanent magnet synchronous motors (PMSMs) may experience chaotic behaviours with systemic parameters falling into a certain area or under certain working conditions, which threaten the secure and stable operation of motor-driven. Hence, it is important to study the methods of controlling or suppressing chaos in PMSMs. In this work, the Takagi-Sugeno (T-S) fuzzy impulsive control model for PMSMs is established via the T-S modelling methodology and impulsive technology. Based on the new model, the control conditions of asymptotieal stability and exponential stability for PMSMs have been derived by the Lyapunov method. Finaily, an illustrated example is also given to show the effectiveness of the obtained results. 相似文献

Permanent magnet synchronous motor (PMSM) displays chaotic oscillation with certain parameter values, which threatens the secure operation of the power system. An improved unidirectional correlation scheme is first proposed to control the undesirable chaotic behavior in PMSM. Simulation analysis shows that the presented control scheme is effective and one can control the PMSM to equilibrium point or non-equilibrium point by choosing appropriate correlation factor. 相似文献
