“…This model was experimentally validated in [ 4 , 29 ]. The experiments selected for the simulated environment were a recreation of the experiments performed in previous works with a real vehicle [ 17 , 18 , 19 , 20 ]: Test 1: A roundabout with a radius of 22 m, at a constant speed of 30 km/h on dry pavement (see Figure 8 ). Test 2: A double lane change at a constant speed of 100 km/h on dry pavement (see Figure 9 ).…”

“…The roll rate

is the observable variable obtained from a gyro-oscilloscope that is already incorporated in current vehicles or from an IMU (Inertial Measurement Unit) located at the center of gravity of a real vehicle. In order for the price of current vehicles not to increase, this sensor can be a low-cost IMU that can give the same performance as high-performance sensors, as presented in [ 18 , 19 , 20 ].…”

“…Furthermore, these systems must be low-cost in order to not increase the price of production of the vehicles. Previous works [ 17 , 18 ] analysed the integration of low-cost sensors in vehicles and the use of these values to estimate the roll angle with the use of different methods [ 19 , 20 ]. These research works demonstrated the feasibility of using these systems.…”

Many of the current research works are focused on the development of different control systems for commercial vehicles in order to reduce the incidence of risky driving situations, while also improving stability and comfort. Some works are focused on developing low-cost embedded systems with enough accuracy, reliability, and processing time. Previous research works have analyzed the integration of low-cost sensors in vehicles. These works demonstrated the feasibility of using these systems, although they indicate that this type of low-cost kit could present relevant delays and noise that must be compensated to improve the performance of the device. For this purpose, it is necessary design controllers for systems with input and output delays. The novelty of this work is the development of an LMI-Based H∞ output-feedback controller that takes into account the effect of delays in the network, both on the sensor side and the actuator side, on RSC (Roll Stability Control) systems. The controller is based on an active suspension with input and output delays, where the anti-roll moment is used as a control input and the roll rate as measured data, both with delays. This controller was compared with a controller system with a no-delay consideration that was experiencing similar delays. The comparison was made through simulation tests with a validated vehicle on the TruckSim® software.
