制动器试验台的控制方法研究

Research on the Control Method of the Brake Test Bench

对于制动器试验台的控制方法以物理学理论及MATLAB应用程序为基础,建立了电动机驱动电流依赖于瞬时转速及瞬时扭矩两个可观测量的数学模型,并对能量误差进行分析,提出了用最小二乘法、追赶法对模型求电流的离散值和进行误差分析的算法.

On the basis of physics theory and MATLAB application program, the article researches the control methods of Brake test rig and builds a mathematical model where motor drive current depends on two significant measure including instantaneous speed and instantaneous torque. The analysis to the error energy has been carried on, and further the algorithm of the error analysis and discrete values of Current model has been put forward by using least square method and chasing method.
