In this chapter, the authors consider the case that the actuators may have imperfect input due to controller quantization, or may suffer from dead‐zone nonlinearity. The occurrence of actuator faults may lead to system performance deterioration and instability and, hence, degradation of safety and comfort. The purpose of the chapter is, therefore, to fill the aforementioned gaps in two aspects. Namely, for heterogeneous vehicular platoons, the authors aim to develop a fault‐tolerant control scheme to deal with actuator faults and find out a new spacing policy to fix the traffic flow instability issue raising from the constant time headway spacing policy. To reduce the conservativeness of traditional quadratic spacing policy, an improved quadratic spacing policy with the lower bound of fault factor is proposed, which can also remove the assumption of zero initial spacing errors.
