Abstract:
In this paper, the cascade control (CC), a structure popular among practitioners in many industry sectors, is used to bridge the two prominent research methodologies in SMC and ADRC for the purpose of multi-axis motion synchronization. In particular, the cascade sliding mode control(C-SMC) is first proposed, from which the cascade active disturbance rejection control (C-ADRC) is derived. This allows the linear and fal-function based nonlinear control actions to be naturally integrated and the controller parameters can be tuned easily with the proposed space-time scaling method. The control law is constructed and validated in multi-axis motion synchronization of parallel mechanisms. The results show that the proposed scheme is effective and practical, with the robustness associated with the bandwidth constraints.
