This paper presents a nonlinear feedback control of the induction motor drive system fed by a matrix converter controlled by a direct space vector strategy. The nonlinear feedback control is an approach privileged, which allows achieving a decoupled control while ensuring a perfect linearization regardless of the profiles of the reference trajectories imposed. In this context, a sliding mode controller has been developed taking the place of the conventional PI controller, in order to improve the performance of the proposed drive system regarding decoupling, pursuit of imposed reference trajectories, and the fast dynamic responses. Moreover, to minimize the harmonic rate injected by the drive system into the grid, a damped RLC input filter was placed upstream with the matrix converter. Finally, a comparison study between the PI and SMC was carried out by simulation. The obtained results clearly indicate the effectiveness of the SMC over the PI controller at different operating conditions, such as load disturbance and speed reversal.

本文提出了一种由矩阵变换器馈电的感应电机驱动系统的非线性反馈控制，该矩阵变换器由直接空间矢量策略控制。非线性反馈控制是一种特权方法，它允许实现解耦控制，同时确保完美的线性化，而不管施加的参考轨迹的轮廓如何。在这种情况下，已经开发了一种滑模控制器来代替传统的 PI 控制器，以提高所提出的驱动系统在解耦、追求强加参考轨迹和快速动态响应方面的性能。此外，为了最大限度地减少驱动系统注入电网的谐波率，在矩阵转换器的上游放置了一个阻尼 RLC 输入滤波器。最后，通过仿真进行了PI和SMC之间的比较研究。获得的结果清楚地表明了 SMC 在不同操作条件下对 PI 控制器的有效性，例如负载扰动和速度反转。
