Embodiment Construction
[0022] like figure 1 As shown, the composite controlled object 1 is jointly constructed by the permanent magnet hub motor 11, the temperature measurement module 12 and the rotational speed and electrical angle calculation module 2, and the input of the composite controlled object 1 is the three-phase control current i for controlling the permanent magnet hub motor 11 a i b i c and the motor winding temperature T 1 and motor case temperature T 2 , the output is the electrical angle θ and the motor speed ω r . Wherein, the temperature measurement module 12 detects the motor winding temperature T of the permanent magnet in-wheel motor 11 1 and motor case temperature T 2 And output, the rotational speed and electrical angle calculation module 2 obtains the electrical angle θ and the motor rotational speed ω of the permanent magnet hub motor 11 r and output. The rotation speed and electrical angle calculation module 2 is composed of a mechanical rotation angular velocity me...
