Please help me find a PID controller coefficient for 1+16.2s/s 1+1/50s. I need P, I, D and N coefficients according to the Matlab formula.

Assuming the Ideal form: 
The PID controller in MATLAB takes the practical form 
, where 
represents the time constant of the derivative filter. The Simulink PID controller block has an equivalent practical form but expressed in N, instead of 
where 
. When the value of 
is very small (or N is very large), the practical PID form closely approximates the ideal PID form.
