- Abstract
This paper studied the problem of stability and stabilization for a coupling permanent magnet synchronous motors (CPMSMs) system with input delay. Input delays caused by communication or calculation were firstly considered in CPMSMs system. Firstly, the mathematical model of the CPMSMs system with input delay and nonlinear constraints was established, in which the input delay is modeled as: time-invariant input delay and time-varying input delay. Then, two novel Lyapunov–Krasovskii (L–K) functionals were constructed for different input delays. Furthermore, based on the proposed L–K functionals, stability conditions and synchronization controllers were derived in the form of linear matrix inequalities. Finally, the effectiveness of the proposed control strategy was shown by simulation results.
