Abstract: The present invention discloses a method for constructing linear luenberger observer for vehicle control. The method for constructing linear luenberger observer for vehicle control comprises the following steps: step 1: building a state-space equation of a driving system of a vehicle to judge observability of the driving system; step 2: dividing the state of the driving system into blocks, and reconstructing state components of the driving system to obtain an rewritten state observation equation of the driving system; step 3: introducing transformation into the rewritten state equation of the driving system to obtain an expression equation and an error equation of the Luenberger observer. The linear luenberger observer constructed by the present invention has low implementation difficulty. High-frequency noise in an output signal of a rotational speed sensor is reduced.
