Numerical results show that the convergence velocity of the complex-mode Galerkin method is higher than that of the real mode Galerkin method for a variable coefficient gyroscopic system.

数值结果表明，复模态Galerkin方法相比实模态Galerkin方法对变系数陀螺系统有较高的收敛速度。

Because of the great elastance of load and deficiency of conventional PID control, variable coefficient PID control method is put forward to improve the pressure control precision of the hydraulic system.

而针对负载弹性较大而常规PID控制方法应用在该系统中有明显不足，本文提出用变系数PID控制方法提高液压系统压力控制精度，该方法简单有效，适合工业应用。

The system with variable coefficient is also discussed.
