Design And Realization Of Analysis System Of The Servo System Speed Characteristics

Speed loop is the indispensable part of servo system for dynamic tracking, for thecurrent loop, its output is the input given of the current loop. the load disturbancerejection and can control the speed fluctuation can be effective to control the inputcurrent effective fluctuation; for the position loop, its input is the output of the positionloop, fast dynamic speed loop tracking response and wide speed regulation range is thefoundation and condition timely and accurate positioning to achieve the position. Thecontrol performance of speed loop will directly affect the performance of servo system,therefore, Dynamic analysis of servo system is a necessary conditions is to design ahigh performance servo system. Now,on the market,The instrument of analysis systemis always large volume, high cost, inconvenient operation and real-time processingability is limited. Therefore, this paper design a software based on VC++6.0which cando analysis of system dynamic characteristicsThe main contents:The main contents of this paper: Using VC++6.0design the analysis system withservo system speed characteristics, the main implementation of the send command ofimportant data acquisition and control of speed and position of the servo system,analyses the characteristics of the data in time domain and frequency domaincharacteristics of servo system, using Mallat algorithm to deal with the data,and Use thesimulation software Matlab verified the feasibility of this method. And according to thedemand design the data storage to save the historical data and the in real time data toanalysis and processing. The characteristics of the speed loop analysis and design-including the characteristic analysis and frequency domain analysis. And the use ofreal-time workshop (RTW) and VC++6in combination with the design of a real-timesimulation system, to verify the correctness and feasibility analysis of the design of PIcontrol parameters. Sending the verified PI controller parameter to the servo controller,so achieve the function of servo system on-line debugging.
