摘要: The effects of various "Stick-Slip" friction models on Proportional+Integral+Derivative (PID) controller stability for a simple system are investigated. Some the more common lack ability to produce limit cycles commonly observed servos subject stick-slip friction. A property is identified which promotes cycle generation, and demonstrated through numerical simulations. This shown be required model useful in predicting behavior simplest systems under PID control. Models lacking this may lead inaccurate prediction dynamics.
