Application of MATLAB Time Domain Analysis and Root Locus Drawing in Control Engineering
At present,automatic control system has been widely used in various fields of human society,and with the development of control theory and technology,the application field continues to grow,but the deduction process of automatic control system formula is more complicated,the calculation is large,and the calculation process is prone to errors,which makes the efficiency low and the analysis of system performance difficult.Manual drawing of step response and root locus is cumbersome.MATLAB is a scientific and engineering calculation software.Aiming at the above problems,this paper uses the functions provided by the MATLAB toolbox to illustrate with typical control systems.It becomes very easy to calculate the performance indicators of the system,draw the step response curve and the root trajectory diagram,and obtain the performance indicators of the system.The advantage of easy computation.Thus,the problem of difficult calculation and complex drawing for automatic control system performance is solved.
