An advanced PID-controller, which allows to increase the quality of regulation. As indicators of the quality of regulation in setpoint regime were used: an average normal integral error; a module of average value of control; overshoot; regulation time. The indicators of the quality of regulation in disturbance regime are: an average normal integral error; a control module mean that stabilizes the controlled variable at the setpoint; a maximum relative error; a minimum relative error; a maximum relative control. Increasing of the quality of regulation has been calculated for objects from second to eighth order (the transfer functions picked up from Åström and T. Hägglund work). The secret - is modification of the integral and differential components of PID-controller.
