【摘要】 针对卷绕物生产过程多电机控制系统间的强耦合、大范围时变的控制难题,该文提出一种基于张力、卷径、惯量观测的自整定解耦控制方法,在对各电机单元间的受力耦合、卷绕单元的时变惯量环节等进行补偿解耦的同时,也使卷绕单元的调节器参数随卷径观测值进行在线自整定,使系统性能基本不受卷径大范围变化的影响。介绍了系统组成原理与具体控制算法,仿真验证了其可行性,最后介绍了基于嵌入式CPU的控制器技术方案。更多还原

【Abstract】 For the problem of strong coupling and wide time-varying among multi-motor control system in the winding production process,the paper put forwards a self-tuning decoupling control method,which based on tension,coil diameter and inertia measurement.It makes the compensative decoupling for the motors units’ force coupling and winding units’ time-varying inertia links.Moreover,the winding units’ regulator parameter is self-tuning on line by the coil diameter observations.These can make the system performance avoid the influence of the coil diameter’s great change.In this paper,it presents the system’s composing principle and specific control algorithm.The experimental results show that the proposed scheme is feasible.Finally,it introduces the controller technical plan based on embedded CPU.更多还原
