Numerical simulation and general analysis of the operation of the hydromechanical automatic control systems of aircraft engine at steady state
Considers the issues of numerical modeling and analysis of generalized work (static mode) pid controller aircraft engine. Mathematical models in nonlinear formulation are presented. The influence of time constants and generalized parameters on the quality of transients and system performance is discussed. In addition, the article clearly demonstrated that a method of transition to generalized variables, using computer simulation, one can obtain results that are not inferior to linear methods. With this approach, the solution significantly reduces the number of arguments of the problem, making the solution easier, and the discernibility of the results has improved. The level of clarity of the results has increased, since the influence of individual factors is not manifested separately, but in the aggregate, and therefore more clearly internal links. The dimensionless variables vary in the range from zero to one, which greatly simplifies the calculation.
