Aiming at the characteristic of nonlinear and natural unsteadiness in rotary inverted pendulum system. This kind of system uses the DSP TMS320F28335 of TI as the control and testing core of this system, adopts DC motor JGB37-3530 and motor drive L298, high precision potentiometer WDY35D4 as sample controller. Angle-to-resistance-to-voltage conversion is achieved by potentiometer, sensors export analog voltage to the first-order filter for filtering noise and transmit signal to the interior of TMS320F28335 and take ADC sample, then use digital filter algorithms to filter the signal again. Finally using double-loop PID control scheme to control motor precisely. Both DSP algorithm and program are implemented by Model-Based Design in Matlab, according to the process of model-simulation-code generation, this rotary inverted pendulum realizes the function of pendulum inverted and rotated. Experiments show this system has a stable and rapid transient process, possesses good stability and resisting disturbance. |
