| 摘 要： | 以平均值模型为基础,通过简化各子模型,得到包含4个变量的状态空间模型,并转化为线性变参数模型.4个状态变量分别是柴油机转速、扫气箱压力、排气管压力和压气机功率.以6S60MC型船用柴油机为例进行了仿真计算,并与平均值模型作了对比分析.结果表明,该模型相对简单而准确,可以直接用于基于模型的控制算法的设计分析.

| Abstract: | A state-space model with four parameters is presented for turbo-charged diesel engines. After simplifying sub models on the basis of a mean-value model, that model was converted to a linear parametervarying model in which the four state parameters are respectively, the rate of revolution of the diesel engine, air pressure at the intake manifold, air pressure at the exhaust manifold and power of the compressor. Using the 6S60MC large marine diesel engine as an example, a system simulation was conducted and the results were compared with those obtained by the mean-value model. Simulation results show that this model is both accurate and simple, and can be used directly for design and analysis of control algorithms based on models. |
