摘　　要：为了更好地调节柴油机转速,采用模型参考自适应控制(model reference adaptive control,MRAC)策略扩展的离散时间积分最小控制综合(discrete-time minimum control synthesize integration,DTMCSI)算法,来达到转速动态快速跟踪和闭环控制稳定的效果。将自适应算法在已完成精度验证的柴油机转速模型上进行仿真验证后,与传统的比例积分微分(proportion integration differentiation,PID)控制策略进行比较,并将该算法在快速控制原型系统搭建的试验平台上进行试验验证。试验结果表明该算法具有快速跟踪转速变化和抗干扰能力,控制性能达到国家二级电站标准,可以实际应用。In order to better adjust the diesel engine speed,the discrete-time minimum control synthesize integration(DTMCSI) algorithm with model reference adaptive control(MRAC) strategy extension was adopted to achieve the fast dynamic speed tracking and closed-loop control stability.The adaptive algorithm was simulated and verified on the diesel engine model,and compared with the traditional proportion integration differentiation(PID) control strategy.The algorithm was tested and verified on the test platform built by the rapid control prototype system.Results show that the algorithm possesses the ability of fast-tracking speed change and anti-interference.The control performance of the algorithm has reached the national second-class power station standard and can be applied in practice.
