坦克全电式炮控系统低速分析和控制

针对坦克全电式炮控系统中存在的非线性摩擦力矩，采用状态变量法和分段线性法分析了其对坦克全电式炮控系统低速性能的影响。结合分析结果，设计了负载观测器，对系统的负载变化进行观测计算，并将观测值引入电流调节器，以补偿由于负载变化对系统造成的影响。仿真和实验表明采用负载观测器能有效减少“爬行”现象，提高系统的低速平稳性能。为改善坦克全电式炮控系统低速性能提供一种可行的设计方案。针对坦克全电式炮控系统中存在的非线性摩擦力矩，采用状态变量法和分段线性法分析了其对坦克全电式炮控系统低速性能的影响。结合分析结果，设计了负载观测器，对系统的负载变化进行观测计算，并将观测值引入电流调节器，以补偿由于负载变化对系统造成的影响。仿真和实验表明采用负载观测器能有效减少“爬行”现象，提高系统的低速平稳性能。为改善坦克全电式炮控系统低速性能提供一种可行的设计方案。

The Analysis and Control of Low Speed of All-Electric Tank Gun Control System

For the nonlinear friction moment existed in all-electric tank gun control system,the factors affecting the low speed characteristic were analyzed using the piece wise linearity and state variable methods.Based on the analyzed results,a load observer was designed to observe and calculate the load change of the system.The observed values were sent to the current controller to compensate the effect of load change on the system.The simulation and experimental results show that the load observer can be used to reduce a ’crawl’ phenomenon and improve the low speed performance of system.A feasible project was provided for the improvement of the low speed performance of all-electric tank gun control system.
