Description

technical field [0001] The invention relates to an angular displacement control device. In particular, it relates to a large-angle displacement control device used in a mechanical system that can realize large-angle displacement control during high-speed operation in the mechanical system. Background technique [0002] Mechanical systems often need to change the phase angle of the control axis to achieve the purpose of improving the overall performance. The control of high-speed and large-angle displacement in traditional machinery is difficult to realize the control of high-speed and large-angle displacement due to the limitation of adjustment time, mechanical structure and motor parameters, thus limiting the improvement of its performance. For example, on an internal combustion engine, if the control of high-speed and large-angle displacement can be realized, the compression ratio can be changed, thereby improving the performance of the engine. When the engine is running...
