[R] nonlinear regression with an iterativ function

we have a function that calculates a value for each day of the year.

For example an iterative function like

actvalue_0 := 0
actvalue_ {t+1} := actvalue_t + f(param_1,param_2,actvalue_t)

and for some days we have measurements. Now we want to choose param_1
and param_2 so that the function values are close to our measured values.

Does anyone know how to solve this problem?
