摘　　要：为了解决某型陀螺寻北仪在初始架设偏差角较大时,粗寻北阶段伺服平台跟踪不上陀螺转速的问题,从硬件电路出发,首先设计了以DSP28027为核心的伺服平台电路,并且引进积分分离的增量式数字PID算法建立数学模型,在CCS3.3中基于此模型编写了软件控制程序,最后在初始架设偏北90°时,对伺服平台的跟踪性能进行试验验证.试验结果表明:伺服平台的跟踪能力可以增大15%左右,并且可以有效提高测速电机的输出能力,具有良好的工程实践性.In the rough north-seeking phase,the servo platform can not be up to the speed of the gyroscope when the initial installation deviation of the gyro north-seeker is large.To solve the problem,a software control program was proposed for servo platform improvement.Firstly,taking DSP28027 as core,a servo platform was designed based on hardware circuit.Furthermore,it was the mathematically modeled by the algorithm for integral separation-based incremental digital PID.Then,a software control program for the model was written in CCS3.3.Finally,the tracking function of the improved platform was tested by setting the initial installation deviation to 90°north.Experimental results showed that the tracking ability of the imporved servo platform was improved by about 15%,and the output capability of the speed measuring motor was also effectively improved.Experiments verified that the proposed method has a good engineerning practicability.
