某单位负反馈控制系统的开环传递函数为 ，要求闭环系统对斜坡输入 ，响应的稳态误差小于 ，相角裕量为 ，剪切频率 为10rad/s时。请采用超前网络来校正原有系统。-A unit negative feedback control system for open-loop transfer function, the slope requirements of the closed-loop system input, in response to the steady-state error is less than, phase margin for the frequency of shear 10rad/s when. Please use the advanced network to correct the original system.
