Abstract

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.

保证非线性不确定电助力器防抱死制动的规定性能控制

电动助力器的控制对车辆安全至关重要。交通事故的发生是由于电动助力器系统无法控制的控制误差和制动力过大导致的轮胎锁死。由于系统的非线性和时变不确定性，实现一致的规定性能和防抱死制动是一项挑战。在这种情况下，本研究为电动助力器引入了一种受约束的规定性能控制（CPPC）方法。我们将规定性能和防抱死制动分别表述为控制误差约束和输入约束。我们提出了一种差分同构方法，在无约束系统和有约束的电动助力器系统之间建立映射。控制设计中不需要线性化，也不需要额外的防抱死系统。实验和模拟证明，在不确定的情况下，可以准确执行所需的制动操作，同时保证规定的性能和防抱死制动。

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.
