A nonlinear control strategy for controlling a motion system with mechanical resonance is presented in this paper. A mathematical model of the servo system is derived according to the parameters of an actual system. By using two Tracking-Differentiators  reference input and system output are tracked and their differential signals are given simultaneously. A nonlinear PD control law in velocity loop is designed based on non-smooth feedback. The simulation results show that the control law is superior remarkably in performance to linear PD control law and the classical PID control law. Tracking-Differentiator resolves the contradiction between rapidity and overshoot of system response. The nonlinear PD control law improves system dynamic performance and intensifies the ability of disturbance rejection. The control design achieved in this paper makes the servo system more robust. 2010 IEEE.

The new design about a CW  digital all-solid-stated LD pumped Nd:YVO 4 controller is introduced. The stable output power of this digital laser controller which adopts Digital Signal Processor(TMS320C31) is approximately 20mW. The whole system is composed of constant- current source  protection circuit  pulse-width modulation circuit  Si-photo-detector and amplified circuit and Digital Signal Processor control system  etc. In terms of error deviation Based on nonlinear control curves of LD power output by Si-photo-detector  the region control can be obtained by means of the PID control algorithm in the software platform  that is  error amendment and high stability laser power output can be achieved. And the precision of temperature control can reduce from 0.2C to 0.04C. By adopted integral separated mode PID control algorithm  the LD output power instability ( %) down to 2%. By way of adopting the new digital design  the work to protect the laser diode  including the continuous adjustable output power with high accuracy and stability  is easily obtained. The internal-external modulation control of the laser power based on digital optical feedback can be accomplished with stable power output. At last  the bringing reasons of noise are analyzed and the solving methods are put forward in this paper.
