摘　　要：为了适应内燃机动力学特性随曲轴转角域的变动要远小于随时域变动的属性,以船舶柴油机为研究对象,针对其转速控制问题,提出了一种基于曲轴转角的自抗扰控制器,其采样和控制通过曲轴转角信号以一定的角度触发。为了更好地验证该算法,采用了一种分缸的发动机模型。在该模型上进行了大量的仿真对比实验。结果表明:曲轴转角域自抗扰控制(ADRC)在跟踪目标转速时对转速变化具有良好的适应性,对外部负载干扰具有优秀的抗扰性。最后通过台架试验对提出的算法进行了进一步的佐证。In order to make use of the traits in internal combustion(IC)engines that the parameters vary less on the crank-angle(CA)domain compared with the time domain,hence,in this paper,a CA based ADRC controller where the sampling and control are executed based on the CA signal is designed for the speed regulation of a marine engine.To verify the proposed scheme better,a cylinder-by-cylinder engine model is employed in this study.On the basis of such engine model,extensive comparative simulations are given to evaluate the excellent control performance of the proposed controller about the speed tracking and attenuating the effect of the load disturbances.Finally,the proposed method is verified again by the bench tests.
