Coordination Based On Can Bus Radar Servo Control Study

Common pitch tracking radar system is drived by the base dual-axis motor,the condition work of the motor is prerequisite for the normal operation of the radar system. Conventional single-axis servo system uses DCS control of non-coupled, although the control is simple, but there is not high tracking accuracy. the system performance of poor coordination of the shortcomings of the system and further upgrade is limited.For this problem, CAN bus is proposed based on cross-coupled coordination of variable gain control mode.Axis servo system by a mathematical model of radar in the analysis of pitch and level of tracking error servo motor servo system on the whole accuracy of the radar based on the variable-gain cross-coupling control algorithm to coordinate the radar servo system control.The simulation proved that the method can improve the tracking accuracy and reduce system errors. On this basis, the system's hardware and software platforms were designed to eventually achieve the desired objectives. The main contents are as follows:1. Model coordinated control system of radar servo system. First, the structural composition of Radar Servo, the establishment of dual-axis coordinated control model.
