在simulink里如何精确建模－好文推荐 Building Accurate, Realistic Simulink Models By Seth Popinchalk An accurate system model is one that performs as expected and produces the desired results. To achieve this level of accuracy you must have a clear modeling goal. For example, will the model be used strictly for simulation, or for generating embedded C code?? This article describes five modeling techniques that can help ensure accuracy: Select the right modeling approach Know your system, understand its dynamics Monitor fo (How accurate modeling in simulink- good text recommended)
