摘　　要：针对车用柴油机转速控制系统存在不确定时滞性,提出变结构鲁棒控制算法.对转速系统的"高速到怠速"功能段进行建模及MATLAB仿真.结果表明控制效果良好,解决了由不确定时滞性引起的系统不稳定问题.The paper presents a reduction-robust control algorithm in order to solve the uncertain time-delay of the diesel engine speed control system. 'From high speed and big torque to idle' is modeled and the control algorithm is simulated with MATLAB. The simulation results show that this controller has good knowable effect and overcomes the instability of the system due to uncertain time-delay.
