摘　　要：针对斩波串级调速系统中控制器的设计问题,提出了基于Laguerre函数的自适应预测控制策略,并对该自适应控制的原理及其算法作了简要概述。被控斩波串级调速系统的实际运行实验表明,该控制系统的设计不依赖于系统精确的数学模型,具备响应速度快、超调量小等优点,并且对于外界扰动和对象参数、结构的变化及非线性具有较强的适应能力。In order to solve the design problem of chopper cascade speed control system, an adaptive predictive control based on the Laguerre function series was presented in which both its principle and algorithm was briefly introduced. The proposed control strategy shows a pretty good adaptability for the system with disturbance, variable parameters, variable structure, as well as nonlinearity. The experimental results demonstrated that the design of the control system does not rely on mathematical models and it has the superiority of strong anti-disturbance capacity, fast response and small overshoot.
