How can I modify the MathWorks code of Particle Filter for nonlinear-​state-esti​mation of a non-homogeneous system (instead of homogeneous) having external input, u(t).

There is a sample code of Particle filter in MathWorks for nonlinear state estimation for the van der Pol oscillator (https://in.mathworks.com/help/control/ug/nonlinear-state-estimation-using-unscented-kalman-filter.html). The external excitation, u(t) of the van der Pol oscillator is zero i.e. homogeneous system.
However, my system is non-homogeneous i.e. u(t) is not zero. So how can I modify the Particle filter algorithm for consideration of the external input signal, u(t) as well as the measurement error covariance of the same input signal?
Thank you.
