In this paper, a compound sliding mode velocity control scheme with new exponential reaching law (NERL) thrust ripple observation strategy is proposed to obtain high performance loop of the linear permanent magnet synchronous motor (LPMSM) system. A controller based on NERL firstly discussed restrain chattering conventional (CERL). Furthermore, unavoidable caused by special structure will bring...

Linear motors have promising application to industrial manufacture because of their direct motion and thrust output. A permanent magnetic linear oscillating synchronous motor (PMLOSM) provides reciprocating which can drive a piston pump directly having advantages high frequency, reliability, easy commercial manufacture. Hence, researching the tracking performance PMLOSM is great importance real...

The permanent magnet synchronous motor (PMSM) is very useful in many applications. Vector control of PMSM is popular kind of its control. In this paper, at first an optimal vector control for PMSM is designed and then results are compared with conventional vector control. Then, it is assumed that the measurements are noisy and linear quadratic Gaussian (LQG) methodology is used to filter the no...

The ironless linear permanent magnet synchronous motor (ILPMSM) is highly compact, easy to control, and exhibits minimal thrust fluctuations, making it an ideal choice for direct loading applications requiring precise positioning accuracy in test rigs. To address the issue of temperature rise resulting from increased primary winding current simultaneously enhance density while minimizing this p...

A liquid cooling plate structure with multiple channels is proposed for linear synchronous motor in this paper. Firstly, a conjugate heat dissipation model established, and coupling analysis fluid temperature fields performed by finite volume method different channel numbers section shapes. The simulation results show that, the capacity of observably improved, especially 6-channels elliptical s...

The complete control design for a permanent magnet synchronous (PMAC) motor, derived from the input-output linearization, is presented in the paper. The motor model, written in the rotor’s d-q coordinates, is nonlinear with respect to the state variables and linear in the control. The input-output linearization makes it possible to write the motor’s model in Brunovski decoupled canonical form w...
