Familiarity with multivariable calculus, linear algebra, and probability and statistics is required.

熟悉多变量微积分，线性代数，概率和统计是必需的。

A decoupling control approach based on inverse system method had been applied for the permanent magnet synchronous motor, which was multi-variable, nonlinear and coupled system. PMSM was decoupled into second-order linear speed subsystem and first-order linear flux subsystem. The servo robust controller was used to design linear closed-loop controller for the pseudo-linear subsystems.
