    Mix Fixed and Variable Step

    To have both variable and fixed step solvers was a condition imposed by the implimentation of the system. The system mentioned is a simple test to figure out how to get the two different types of sovlers to work together. The actual system is a vibration platform which consists of a vibration...

    Right. It seems that the free-running counter which is linked into another library was causing the error. Replaced with the digital clock from Simulink Extras, couple of rate transitions and bang, simulation is back on track. Savouring short-lived satisfaction. Head no doubt to soon be smahing...

    Warning: The model 'SCM2' does not have continuous states, hence using the solver 'FixedStepDiscrete' instead of solver 'ode4'. You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or setting 'Automatic solver...

    I think the problem may have something to do with selecting the 'Inline Parameters' check box for model referencing..

    Mix Fixed and Variable Step

    Hello I am attempting to model a simple mass-spring-damper system with PID contol. I am attempting to run the MSD side of things in a simulink model block with a variable step solver and the controller in a separate fixed step model bloack. The top model which contains the both of the two model...
