Aerial working platforms are widely used to transport personnel and equipment to a specified height. To ensure operation stability, their chassis are supported on the ground by a four-legged outrigger system before use. At present, leveling of an aerial working platform is manually conducted, resulting in low accuracy, low efficiency, poor robustness, and poor adaptability. In response to this, a battery-electric drive-electric control integrated aerial working chassis is proposed at first. Then the attitude and load coupling control model proposed by our team is applied to design its integrated control system. Finally, performance tests of the control system and comparisons with the traditional point-chasing method are studied. Results show that the aerial working chassis and the control system can rapidly and synchronously realize the geometry leveling and load homogenization of the chassis, thus having potential values to be promoted to special vehicles with leveling requirements.
