摘要
为解决经编机电子横移系统中存在的磁链谐波扰动、摩擦力扰动等内、外部扰动引起的参数摄动问题,使得针对精确模型的控制手段能够满足控制要求,提出了利用模型参考自适应控制策略进行控制器设计,并进行仿真实验。结果表明,与PID控制方案相比,模型参考自适应控制策略不仅能够保证闭环系统的全局稳定性以及对参考模型的精确跟踪,而且能够很好地抑制模型参数的不确定性对控制效果带来影响,验证了控制策略的有效性。
Since disturbances such as friction and harmonic exist in warp knitting elec tronic transverse systems, causing parameter perturbation, the requirements of the control strategy of a precise model cannot be met. A model reference adaptive control strategy is pro posed and used to design controllers. Simulation results indicate that, compared with the PID method, the model reference adaptive control strategy can ensure global stability of the closedloop system and the precise tracking of reference model, and can also reduce influence on the control due to uncertainty of model parameters.
