摘要
速率环控制器是稳定平台三环控制的重要环节之一,其参数整定部分是实现电机理想调速的关键。为缩短整定周期,提出了基于DSP的智能辨识方法,该方法利用力学原理式、力矩电机电枢电压平衡方程式以及电磁作用方程式推导建立速率环控制器模型,并基于DSP通过多元线性回归方法实现全自动智能参数整定。实验结果表明,用速率环调节方法获取的参数能使指令速率与实际执行速率基本吻合,具有一定的可行性。
Speed loop controller is an important part of three-loop control method used in stabilized platform.Its parameter setting is the key to the precise speed control.To shorten the cycle of setting,an intelligent identification method based on DSP is introduced,which uses formula involving mechanics principle,armature voltage balance equation and electromagnetic equation to establish speed cycle controller model.Through multiple linear regression method embedded into DSP,the automatic intelligent parameter setting is realized.The experimental result shows that output is almost the same with the instruction with the method of speed-loop adjustment,thus the method is feasibility.
