摘　　要：为更加简捷高效地实现惯导计算机的程序编排,提出了一种新的指北方位惯导系统统一控制方程。通过改变系统控制方块图的结构,将无阻尼惯导系统和阻尼网络人为分离,阻尼网络的输出可视为系统的干扰项。系统控制方程始终采用无阻尼条件下的表达式,惯导系统控制方程和阻尼网络可以实现模块化设计,使控制方程的实现形式和推导过程大为简化。无阻尼、水平阻尼和全阻尼状态的控制方程,只需三个参数即可实现统一表达。给出了惯导计算机的运算流程,并分别对五种状态下的指北方位惯导系统做了仿真实验。仿真结果表明:新的统一控制方程与传统的一体化设计方案等效。To simplify the programming of north-oriented INS（Inertial Navigation System） computer,a new kind of INS uniform control equations are proposed.By changing the strucyure of the system block diagram,the undamped INS control equations are separated from damping net,and the output of damping net is treated as disturbance for INS.The INS undamped mode equations can be used in all kinds of conditions.The design of control equations and damping net would be modularized,which enormously simplifies the realization form and deduction process of control equations.Only three parameters are needed to unify the INS equations in undamped mode,horizontal damping mode and absolute damping mode.The flow chart of computer operation progress is established.The INS simulations in five different damping modes are also made,which show that these uniform control equations,which combine the undamped INS and damping net in an incorporate block diagram,are equivalent to the old uniform control equations.
