Abstract

The embodiment of the invention provides a slip and trackslip rate linear control method and device and an anti-brake and traction control system. The slip and trackslip rate linear control method comprises the steps that nonlinear control target functional is constructed based on an affine nonlinear dynamic model; according to a nonlinear transformation equation set, a nonlinear dynamic model topology is equivalently converted into a linear state space model, and the nonlinear control target functional is converted into a linear control target functional according to a nonlinear transformation equation set or the linear state space model; according to the principle of the minimum, a first solving equation is constructed, a first analytical solution is obtained according to the equation, and the first analytical solution is subjected to nonlinearly mapping into a second analytical solution; and a second solving equation is constructed according to the principle of the minimum, when thesecond analytical solution enables the second solving equation to be true, the second analytical solution is taken as the optimal slip and trackslip rate and torque controlling amount, and the linearcontrol over the slip rate of the anti-brake control part of the system and the trackslip rate of the traction control part of the system is realized.

Description

technical field [0001] The present application relates to the field of control technology, in particular, to a slip slip rate linear control method and device, and an anti-lock and drive anti-skid control system. Background technique [0002] ABS (Anti-Brake-System, automatic anti-lock braking system) and TCS (Traction-Control-System, drive anti-skid system) are anti-lock braking and anti-lock braking systems for wheeled devices that are widely used in electromechanical composite systems such as aircraft, railway trains, and automobiles. Drive anti-skid control system. Taking the change rate of the slipping rate of the wheeled device as the control target, the braking and driving force control algorithm of the electronically controlled braking drive system can be reasonably designed to prevent the wheeled drive from being damaged during emergency braking. Locking, the function of preventing slippage when driving forward on wet and slippery roads, and finally achieves the pu...
