Abstract


The economic crisis can not stop the trend of the rapid development of the global economy, and how to balance economic development and non-renewable energy consumption between the contradictions become imminent. The way to solve the energy problem for energy conservation and the development of new energy sources, which is today's hot. The secondary conditioning system for the purpose of high utilization and energy efficiency, recycling and reuse of the energy of the system. The pursuit of high profits in the enterprise today, secondary regulation system to be taken seriously. In this context, the selected secondary control to adjust the speed of the system with the theoretical and practical significance for the research direction. First of all, the status quo of the current domestic and international secondary regulation technology of secondary regulation system features and applications in the industry, and possible future application prospect. Secondary regulation control of the system is divided into the speed control, power control and torque control, speed control is the most basic, the most common but also most likely to achieve control, so this article using the speed control mode. Secondary regulation system for speed control, a more detailed description of its structure, it works to establish the mathematical model of the system, on the basis of derivation, and laid the foundation for the study of the following control strategies . Second, read a lot of literature on the basis of the control algorithm is designed for secondary regulation system. In order as soon as possible to promote the use of advanced control methods and industrial control method, fuzzy PID controller design. Fuzzy sliding mode controller design for variability in the secondary to adjust the speed of the system parameters, especially the change of the moment of inertia and damping, as well as the presence of outside interference. Strong robustness and fuzzy sliding mode controller using sliding mode algorithm is not sensitive to parameter variations and external interference to ensure speed stability, while taking advantage of the the fuzzy algorithm weakened chattering sliding mode control. The application of two control algorithms were simulated, and achieved good control effect, increase the system's adaptive force and the ability to regulate the environment changed. Finally, secondary regulation Yanshan University the integrated bench on the basis of the hydraulic system, of experimental secondary regulation speed control system, proved the feasibility of the previous theoretical analysis and simulation comparison.
