The aim of this article is to explore the dynamic characteristics and stability of the permanent-magnet synchronous motor (PMSM). PMSM equilibrium local stability condition and Hopf bifurcation condition, pitchfork bifurcation condition, and fold bifurcation condition have been derived by using the Routh-Hurwitz criterion and the bifurcation theory, respectively. Bifurcation curves of the equilibrium with single and double parameters are obtained by continuation method. Numerical simulations not only confirm the theoretical analysis results but also show one kind of codimension-two-bifurcation points of the equilibrium. PMSM, with or without external load, can exhibit rich dynamic behaviors in different parameters regions. It is shown that if unstable equilibrium appears in the parameters regions, the PMSM may not be able to work stably. To ensure the PMSMs work stably, the inherent parameters should be designed in the region which has only one stable equilibrium.

“…Subsequently, this control approach has been extensively used in other control applications. Much of the reported literatures used CCC to deal with the velocity synchronization problem, such as in [32] and [33]. Significant efforts have been made in utilizing the CCC to solve the position synchronization of multiaxis system [8], [34]- [36].…”

In this paper, a novel dynamic decoupling-based robust synchronous control scheme is proposed for the high-precision motion trajectory tracking control of a hydraulic parallel manipulator. The presented controller is derived by effectively integrating joint disturbance rejection technique with a cross-coupling control (CCC) approach. The parallel manipulator is first considered as a multi-axis system with modeling uncertainties and strong nonlinear coupling dynamics. For each axis, two extended state observers are synthesized to estimate and reject both the matched uncertainties and unmatched uncertainties (e.g., external disturbances and unmodeled nonlinearities), and then the decoupled dynamic model of the system in joint space can be established. A synchronization error is developed to represent the coordination degree of multiple actuators and then coupled with the position error to form a coupling position error. Subsequently, based on the system decoupled dynamic model, a synchronous controller with the feedback of coupling position error is carried out to coordinate the motions of actuators by combining the CCC strategy with robust control via backstepping method. The proposed controller can theoretically guarantee the simultaneous convergence of both position tracking errors and synchronization errors. The stability of the system is verified via the Lyapunov method. The comparative experiment results are obtained to verify the high tracking performance nature of the proposed control strategy. INDEX TERMS Hydraulic parallel manipulator, extended state observer, decoupled dynamic model, cross-coupling approach, robust synchronous control.

This study focuses on the coordination control problem of multiple electrical excited synchronous motor systems. A robust coordination controller is designed on the basis of cross coupling and an interval matrix. The proposed control strategy can deal with load uncertainty. In addition, the proposed control strategy is applied to a high-power metal-rolling system. Simulation and experiment results demonstrate that the proposed control strategy achieves good dynamic and static performance. It also shows better coordination performance than traditional proportional-integral controllers.
