Research Of Robust Control System Of Diesel Generating Set Based On H_∞ Optimized Design

With the high speed of modern control theory developed,there are many different control algorithms,different control algorithms have their own different advantages and disadvantages,for different types,different states of the system,we should carefully choose different control theory and methods.In modern control theory,optimal control is one of the most important and basic components.It mainly studies the optimal control law according to the dynamic characteristics of the controlled system,and works according to certain technical requirements to make the performance index of the system reach the optimal value in a certain sense.Robust control is one of the more mature and more control methods in optimal control.In this paper,based on the analysis of robust control system,the mathematical model of diesel generator set transient and diesel engine speed control system is established by some relevant design steps.Speed control system for H∞ control design and MATLAB/Simulink simulation.The simulation process includes the optimization of H∞ control parameters,the change of different parameters and the influence of load change on the output of control system.At the same time,compared with the traditional PID control mode and the control system for the control mode,the simulation results are compared with the traditional PID control.The stability time is short and the precision is high.Perturbation can still be stable when the control system.Robust control can deal well with the actual control system in production and engineering that can not satisfy the uncertain state of the hypothetical state,which is closer to the practical application of engineering.Consider the use of embedded systems,the actual system for real-time control and monitoring,analysis of hardware and software design content and steps.
