A type of pneumatic force servo system is discussed in this paper. In this system, output pressure depends on pressure difference between two chambers of cylinder; by controlling pilot-operated reducing valve will get different cylinder chamber pressure. Dynamic mathematical model and control Strategy of this system is founded in this paper. By mathematical model and control Strategy, the digital simulation results show how system performance with different gas source pressure and rodless cavity size..

The Way

In order to obtain higher cam quality, the research on the cam contour error is studied. The cam is machined in the way of X-C biaxial linkage motions. The linear motor drives the grinding wheel mechanism to get the motion of X axis, and the motion of C axis is the rotating of cam driven by the torque motor. Because of the servo-system-lag of the two axes, the cam contour error is formed in the X-C biaxial linkage motions. Moreover, the following position error of X axis and C axis is not same as the cam contour error. The relationship between axis following position error and cam contour error is studied. The mathematical model of cam contour error is constructed, the relationship between the cam contour error and the following position error are obtained. At last, the conclusion which the cam contour error can be controlled is made, although the following position error exists at the same time. To design the contour error controller for higher quality cam is based on the above conclusion.

Nonlinear Robust

Nonlinear robust controllers were proposed for permanent magnet linear servo system. In order to reach accurate track of the motor speed and current, an error system dynamic equation based on the motor nonlinear mathematical model was established. The track and disturbance suppression was summed up the design of nonlinear robust controllers. Two theories used in describing nonlinear robust controllers were obtained by defining proper storage function. The equations of nonlinear robust controllers which met disturbance suppression and asymptotical stability were proved. The results of simulation test indicate that the linear servo system with nonlinear robust controllers can guarantee disturbance suppression and the tracks of input signal.

Perturbation Effect

In order to improve the friction nonlinear perturbation effect on shipboard antenna tracking, first to a certain type of ship azimuth servo system as an example, considering the establishment of a mathematical model with friction, and the model is carried out using PID control method. The results show that with friction disturbance considered, there are tracking exist "flat top" phenomenon and large tracking error, and when the speed is low, there is the "crawl" phenomenon.Keywords: ship servo system, friction disturbance, disturbance compensation
