“…Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels [13]. From the Figure 5, as the car which is auto body of this system moves along the road, the vertical displacement at the tires act as the motion excitation to the automobile suspension system.…”

Fault tolerant control system (FTCS) provides an efficient technique to ensure the system goal to be achieved in spite of faults. This paper proposes the application of model based sensor fault tolerant control system for truck pulling a trailer system, an automobile suspension system and filedcontrolled direct current (DC) motor system. The fault tolerant control design is divided into two parts which are a nominal performance controller and a model based element to provide sensor fault compensating signals. In this paper, the PID controller is used as a nominal controller that specifies the performance specification. When a sensor fault is present, the controller input is augmented to compensate the fault. Simulation results of real time implementation for truck pulling a trailer system, an automobile suspension system and field controlled DC motor system shows the effectiveness of the proposed design.Keywords-sensor fault tolerant control, model based, truck pulling a trailer system, automobile suspension control system, and fieldcontrolled DC motor system.

“…These works have as common point the use of control design conditions based on Lyapunov functions. In [1] and [9], permanent magnet linear actuators are used in order to have also recover of energy by means of the suspension and this is a field of interest for research. In [13], a linear actuator is used and a lead lag, an LQ and a fuzzy based controller are compared for disturbance rejection, with simulation and experimental results, pointing out the good rejection properties of the fuzzy controller, but mentioning that the design of this controller is a difficult task.…”

“…Several works have been recently published on control design of active suspension systems [1], [8], [9], [10], [11], [12], [13]. In [8], H ∞ control was used with pole location constraints to get optimal rejection of disturbances for a second order model of an active suspension.…”

This paper develops an optimal H∞ state feedback controller for a quarter-car active suspension system application. The plant parameters and performance requirements are borrowed from a prototype in the literature. The control design is done using convex optimization with linear matrix inequality constraints, which ensures a very fast and efficient computation of the controller, without trial and error procedures for control design. The results of the closed-loop system with the proposed controller prove to be attractive in terms of high attenuation of disturbances lying in the range of frequencies of typical disturbances for this application. Comparison with a controller from literature to cope with the same problem illustrate the superiority of the optimal H∞ controller. Moreover, for the parameters used in the paper, one of the gains of the controller can be made equal to zero, leading to a control implementation with no dependence on availability of the disturbance for feedback, which is very interesting from practical point of view, since the measurement of the disturbance, a difficult task, could be avoided in the control implementation. The evaluation of the closed-loop system on time and frequency show how the controller designed for optimal rejection of disturbances can be interesting for the application.
