MFAC Based Speed Controller Design For Electric Transmission Of Tank

With the development of military technology, tank, as the Army's main weapons, must have higher performance. The development potential of traditional mechanical tanks is closing to the limit, while electric transmission tanks show great vigor in the future development. Compared with the traditional mechanical transmission, electric transmission, in mobility, energy efficiency, etc., shows many advantages. Electric transmission is a technology which uses generator set and battery set driving motor to travel and achieve various functions in tank movement. Driving motor and its control system, which convert electrical energy into mechanical energy to drive the tank, is the major system in the electric transmission tank. DC motor is firstly applied as the driving motor in electric transmission tank.Model-free Adaptive Control (MFAC) is a kind of controller design method which need less knowledge of mathematical models and relevant prior knowledge, and only need system I/O data to design the controller. It has many advantages such as fewer estimated parameters online, simple to design and easy to implement. And especially for some strongly nonlinear and strong coupled systems whose models are difficult to build, MFAC has good control Performance. Compared to the method which need mathematical model, MFAC has the incomparable advantage.In this paper, we consider brushless DC motor as the research objective and MFAC is applied to the electric transmission speed control system. The speed controller based on MFAC is constructed. And we establish tank simulation models to simulate the control system use MATLAB. The effectiveness of the proposed control scheme is verified. Compare to the traditional PID controller with simulation results, the MFAC shows its advantages.
