Abstract


With the development of military technology , the tanks as the Army's main battle weapons , its performance increasingly high demand , the development potential of the traditional mechanized tanks already close to the limit , the electric drive tanks as the main mode of development of future tanks , shows vigor . Compared to traditional mechanical drive systems , electric drive showed many other advantages in terms of mobility , energy use efficiency . Electric drive technology is the use of the generator set and the battery pack , the traction drive motor to the time of completion of the tank driving power transfer technology to achieve the various functions that are involved in the process of the tanks motorized . Drive motor and its control system , which converts electrical energy into mechanical energy to drive a tank , it is important systems of the electric drive tanks , which the DC motor is one of the earliest applications of the tanks Electric Drive drive motor . DC motor running load and environmental parameters , so that the speed of change was uncertainty , coupled with the non-linearity of the motor speed the process itself , to accurately identify the dynamic process model parameters and build a mathematical model of the system very difficult. Model - free adaptive control is a need not controlled system mathematical model and a priori knowledge , the only system I / O data to the controller design method , the online estimation parameters simple design , easy implementation difficult to model strongly nonlinear , strong coupling system has good control , has the incomparable advantage compared to reliance on the mathematical model of the system control method . Brushless DC motor , the model-free adaptive control applied to the tank electrical transmission speed control system , designed to speed controller based on the model - free adaptive algorithm and through experimental simulation of MATLAB software , verify the mentioning the validity of the control scheme . Compared with the experimental results of the conventional PID controller , showing that the model - free adaptive algorithm has superiority .
