A decoupling control based on the bi-regulation principle of growth hormone

Since the conventional decoupling algorithms are complicated and difficult to be implemented, we present a bio-imitated decoupling controller based on the bi-regulation principle of growth hormone (GH), and provide its decoupling algorithm. It has two or more control units. Every control unit consists of a control module, a decoupling distributing module, and an output module. These units communicate with each other to exchange control information, and then adjust the actuators harmoniously. The decoupling algorithm is simpler than any other decoupling algorithm, and can be implemented more easily. As a result, the process can be controlled stably, and the coupling influences among the various loops can be removed. Simulation results demonstrate that the decoupling scheme can completely eliminate the coupling influence, and has better control performance
