    Abstract: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.
