Trying to work with particle filter function and would like to ask if Transition function vdpParticleFilterStateFcn Can use unknown parameters the same way as State Space Model functionality? If it can, can I do the estimation with some ssm analogue?

The transition function may use unknown parameters. You can create custom transition function by using source code of vdpParticleFilterStateFcn and add unknown parameters (by defining them as NaN) in the function code.

I do not think you have to write any complicated code for likelihood estimation. You can use the inbuilt functions such as vdpMeasurementLikelihoodFcn or create a custom function by using the source code for the same.
