This paper investigates the problem of finite-time sampled-data control for permanent magnet synchronous motor system (PMSMS) with input time-varying delay. First, a novel state space equation of PMSMS is obtained by choosing suitable state variables to the system attribute of PMSMS model. Then, based on the obtained state space model, the problem of finite-time sampled-data control design is addressed for uncertain PMSMS. By implementing a proper novel Lyapunov–Krasovskii functional together with linear matrix inequality optimization technique and Wirtinger-based integral inequality approach, a new set of delay-dependent sufficient condition is derived which guarantees the robust finite-time stability of the closed-loop PMSMS. Based on the obtained condition, an explicit expression for the desired controller can be established in terms of matrix inequalities. Finally, the effectiveness of developed control technique is validated via simulation results.
