The Dynamic Regulator that is Robust to the Object of Control Varying

This paper describes the problems with the dynamic regulator utilization while parameters of the object of control vary. Existing dynamic regulator realizations suppose that the object of control is time-invariant, and are capable to remove steady-state errors connected with the disturbances. Improved realization of the dynamic regulator is suggested that includes the gain that plays a role of decreasing factor. The decreased value of the input variable is summed with the output of the integrator that accumulates the value of control error. This decrease removes overshooting while the parameters of the object of control vary. The method to find out the values of decreasing factor and quality factor of the integrator is suggested. The computational experiments were carried out and their results show that improved dynamic regulator has transient performances without overshooting, while the parameters of the object of control vary in the range from −15% to +15%. If the duration of the transient process is not critical this range may be made wider.
