Although the quality and quantity of mobile anti-aircraft gun systems remains unknown, there is no indication of any mobile surface-to-air missile systems other than man-portable systems such as the SA-7 and SA-14 or SA-16 entering the inventory to augment North Korea's static air defense umbrella.

虽然质量和数量的移动高射炮系统仍然未知，目前并无迹象显示有任何的移动型防空导弹的系统以外的其他单兵携带系统，如的SA - 7和SA - 14或SA服务-16进入库存，以加强北朝鲜的静态防空保护伞。

But in fact, the system of half-tracked air-cushion vehicle is over complicated. When the vehicle drives in an unknown soil, the parameters and structures of controlled member will change with load or disturbances. This system is nonlinear and time-variant, and it is very difficult to analyze its transfer function and state function quantitatively.

然而在实际工作中，由于本课题中的系统过于复杂，当行驶在未知土壤条件下时，被控对象往往随着载荷或干扰因素影响，其特性参数或结构发生改变，属于非线性和时变性的不确定系统，它的传递函数或状态方程难于用传统的定量分析方法加以实现。

In order to prove the reliability, test studies have been primarily carried out in the indoor soil bin. The data of the vehicle driving state parameters under the same or different terrain are analyzed. The process curves are compared by different control schemes. The theoretical model of the optimum driving state is reliable and fuzzy control scheme is feasible. The disturbances and unknown factors of control system are analyzed. Test results prove that the half-tracked air-cushion vehicle can drive steadily under control of the computer. At the same time the sensors used to measure soil mechanics characteristics on line need to be developed. And it is the important problem to be solved in the future study. The necessary regulation and correction are put up. So the studies in this paper provide some instruction for the further research work.

为了验证本文提出的最佳工作状态及最佳垫压理论，并分析控制系统的可靠性和稳定性，本文在半履带式气垫车的模型车上，在室内土槽中进行了初步的实车性能和理论验证试验，考察了在同种和不同土壤条件下气垫车的行驶状态参数的测量数据，比较了采用不同控制方法下的过程曲线，验证了最佳工作状态的理论模型和模糊控制系统方案的可行性与可靠性，从而保证了采用自整定模糊PID控制器能够使半履带式气垫车在稳定行驶最佳工作状态下；同时通过试验研究，分析了系统中各干扰与未知因素，对控制方案进行了相应的调整和修正，为今后进一步的研究工作提供了一定的指导。
