Recent advances in multi-axis control systems highly rely on new control algorithms and system architectures. The system-on-chip technology is able to realize the novel multi-axis control systems efficiently. But the system-on-chip design and implementation are still challenging and time-consuming for most control system practitioners. This article presents a system-on-chip-based solution for multi-axis control systems. With the high-level synthesis technology, the proposed system can be used as a rapid prototyping for multi-axis control or a test platform for modern control algorithms. A study case of the proposed solution is given to prove its feasibility. The advantage of this implementation is efficient system integration with rich functionality due to the high flexibility of system-on-chip. In order to verify the proposed solution of using system-on-chip to implement modern control algorithms, a mixed H 2 / H ∞ state-feedback robust controller via linear matrix inequalities is designed for multi-axis synchronization. Experimental results are shown to prove the efficiency of the proposed system-on-chip-based solution.
