摘要：
An embedded pneumatic servo DSP controller was designed in view of the deficiency of the existing embedded pneumatic servo controller software. The model of proportional direction valve controlled cylinder system was established, which adopted adaptive robust control strategy designed by back-stepping method. Online parameter estimation improved the tracking precision further in steady state. Control algorithm design and simulation was conducted in the tool of MATLAB/Simulink based on Model Based Design method. The controller software could be generated automatically and rapidly after series of model transformation, and was combined with DSP hardware driver and PC monitor. Control software experiments were conducted to verify the performance. Results showed that the pneumatic DSP servo controller trajectory tracking control error was within 5%, and the duration of control was up to 1 ms. © 2017, Zhejiang University Press.
