Aerial work platform is a kind of special aerial work machinery used for lifting the operator, tool, material to the specified location by platform for the installation, maintenance and other operations. Aerial work platform has been widely used in daily social life with economic development. Aerial work platform is required for fast, large-scale operation in order to pursuit the larger operation range and higher operation efficiency, but fast, large-scale operation is bound to bring some security risk. In order to avoid the loss caused by accidents, the higher safe performance of aerial work platform is required when pursuing efficiency. Aiming at the safe operation of aerial work platform, the key control technologies for safe operation of aerial work platform are explored in this thesis. Some relevant topics such as design of intelligent control system for aerial work platform, anti-rollover control and early warning for aerial work platform, anti-rollover control for self-propelled aerial work platform, vibration suppression for light weight long beam aerial work platform and anti-sway control for aerial work platform used for lifting are discussed. The main contributions of this thesis include following issues: Firstly, a kind of amplitude restricted anti-rollover control method is proposed for the anti-rollover control issue of telescopic aerial work platform. The safe operation work space of aerial work platform is derived by dividing the amplitude restricted areas and kinematic analysis of the telescopic boom. The amplitude restricted threshold is derived by the safe operation work space. The anti-rollover monitoring and early warning for telescopic aerial work platform can be achieved by comparing the real-time amplitude and amplitude restricted threshold in actual control system. Secondly, a kind of anti-rollover control method for self-propelled aerial work platform is proposed for the anti-rollover control issue of self-propelled aerial work platform. The linearized model is obtained through the establishment of self-propelled aerial work platform model. The position control of chassis in the model is achieved by using full state feedback and the motion control law of boom in the model is derived by introducing the ZMP theory as restrictions for boom movement. The anti-rollover control of self-propelled aerial work platform is achieved by tracking the trajectories of chassis model and boom model. The anti-rollover control method is verified...
