摘　　要：本文将线性二次型最优控制技术运用在非线性系统的发动机燃料控制领域,使求解偏微分方程的燃料控制量能够通过简化的代数解析式加以求得,从而可由工业控制微机具体实现。文章阐述了在发动机台架试验的基础上发动机燃料输入、功率输出动态模型的建立以及运用计算机仿真技术对设计的最优控制系统进行的试验结果。This paper is written on the application of linear quadratic optimal control techniques for fuel control of nonlinear engine system and establishes the engine fuel control systems. By using means of the simplified partial differential equations, the fuel output of the systems is conveniently calculated so that fuel control can be performed by industrial microcomputer controller. Meanwhile, on the basis of engine test results, the dynamic models of a series of fuel-in and power-out state equations have been obtained and the fuel optimal control systems have been tested with computer simulation.
