Abstract
An embedded nonlinear cooperative pulse-controller (ENCPC) is characterized in that its control algorithm module comprises a comparison module, an identification control unit, a dynamic control unit, a steady-state control unit and a cooperative control unit. The comparison module generates control errors. The identification control unit identifies the model parameters, the time constant and the delay time. The dynamic control unit rapidly reduces the control errors, improves the rise time and decreases the overshoot of the control system. The steady-state control unit further eliminates the control errors in a steady change process and improves the control precision. The cooperative control unit coordinates and generates the final control output signal. The control algorithm module of the ENCPC enables that the ENCPC can quickly and stably eliminate the control errors with short rise time, small overshoot and short settling time.
