摘　　要：主动悬架控制器的设计中引入了一种新型研究方法,缩短了主动悬架控制系统的开发周期。采用MATLAB/Simulink/RTW(Real-TimeWorkshop)为软件开发环境,采用xPC结构配置目标硬件,将通用PC转化为实时控制器,搭建开发平台建立了被动悬架、线性二次型高斯(Linear Quadratic Gaussian,LQG)主动悬架和模糊控制主动悬架的Simulink模型,利用RTW工具箱从Simulink模型自动生成可执行代码,下载到xPC环境的目标PC上采用外部模型运行,得到仿真结果,在时域范围内采用均方根值(RMS)法对3种悬架模型的性能加以分析对比。A new research method is introduced to the design of active suspension controller, by this method the development cycle can be cut down. Using MATLAB / Simulink / RTW （Real-Time Workshop） for the software development environment, and xPC target for the hardware structure. Then transform the generic PC to the real-time controller. After that three simulation models of active suspension are established including a passive suspension model, an active suspension model with LQG （Linear Quadratic Gaussian） Controller and an active suspension model with FLC （Fuzzy Logic Controller）. The executable code is generated automatically by using the tool box based on the Simulink model. Then download the code to the PC under xPC environment that using an external model. Finally, the simulation results of three types of suspension model are analyzed and compared in the time-domain by RMS method.
