Prescribed performance control guaranteeing anti-lock braking for nonlinear uncertain electro-booster
Control of electro-booster is crucial for vehicle safety. Traffic accidents occur due to unmanageable control errors in the electro-booster system and tire lock-up caused by excessive braking force. Achieving consistent prescribed performance and anti-lock braking presents a challenge due to the system nonlinearity and time-varying uncertainties. In this context, this study introduces a constrained prescribed performance control (CPPC) approach for the electro-booster. We formulate the prescribed performance and the anti-lock braking as constraints of control error and input, respectively. A diffeomorphism approach is proposed to establish a mapping between an unconstrained system and the electro-booster system with constraints. No linearization are invoked in the control design and no extra anti-braking system is needed. Experiments and simulations have demonstrated that the desired braking actions can be accurately executed under uncertainties, while guaranteeing both prescribed performance and anti-lock braking.
期刊介绍：
The International Journal of Non-Linear Mechanics provides a specific medium for dissemination of high-quality research results in the various areas of theoretical, applied, and experimental mechanics of solids, fluids, structures, and systems where the phenomena are inherently non-linear.
The journal brings together original results in non-linear problems in elasticity, plasticity, dynamics, vibrations, wave-propagation, rheology, fluid-structure interaction systems, stability, biomechanics, micro- and nano-structures, materials, metamaterials, and in other diverse areas.
Papers may be analytical, computational or experimental in nature. Treatments of non-linear differential equations wherein solutions and properties of solutions are emphasized but physical aspects are not adequately relevant, will not be considered for possible publication. Both deterministic and stochastic approaches are fostered. Contributions pertaining to both established and emerging fields are encouraged.
