Electric micro tillage machine research and development experimental device and method

The invention discloses an electric micro tillage machine research and development experimental device and method, using an experimental device including a motor controller and an online acquisition system, and cooperated with an electric dynamometer test bench. When using, the online acquisition system is used to collect the input voltage and current of the controller and a motor speed signal output by the controller; then a power system is installed on the electric dynamometer test bench, the voltage input to the controller by a battery simulator is adjusted, and the voltage is adjusted in the same interval unit in sequence, so as to test the dynamic characteristics and efficiency characteristics of the power system at different voltages; then expected corresponding relationships betweenparameters and electrical signals under different working conditions and tool conditions are obtained; the electric micro tillage machine research and development experimental device and method are used to match the power sy
