查询词典 in-line antenna

Servo controller is key part of antenna control system.In some servo controller,classic PID control algorithm is adopted. In order to improve precision of control system,the integral parameter has been turned too big to use because it will cause integral saturation which depress system performance.On the other hand,ISA bus is used to communicate between servo controller and main computer.ISA is low speed interface protocol,it cannot provide more data for complicated real time position control in servo controller.
