Popis: | A pneumatic artificial muscle (PAM) position servo system driven by fast switching on/off solenoid valves is proposed. According to the active disturbance rejection technology, a second order active disturbance rejection controller (ADRC) is designed. Using absolute angle encoder to measure the position of PAM, then the ADRC generates the desired duty cycle pulse-width modulation (PWM) signal to drive the high-speed on-off valve. The step, square and sinusoidal input signal tracking tests are carried out on the system, and the results are compared with the proportional-integral-derivative (PID) control system. The experimental data analyses show that the ADRC is better than the PID controller. It has the characteristics of fast response and high control precision, and can meet the control requirements of pneumatic artificial muscle. |
