“…The SOF controller is defined as (12). Since the suspension stroke and its derivative are available for SOF control, the vector of sensor outputs is defined as y as given in (13) from the output matrix C and the state vector of (6). Because there are two sensor outputs, the dimension of the gain matrix, KSOF, is two by one.…”

“…An active suspension system has been used to reduce the road-induced vertical acceleration and improve the ride comfort by exerting a control force with some actuators. To date, so many papers have been published to design and implement a controller for active suspension [5][6][7]. Most of these papers have adopted only feedback control.…”

“…The laser contact point of this sensor is set to a position 1.4 m forward of the center of the front axle [27]. Active Body Control (ABC) developed by Mercedes-Benz in 2007 has laser scanners used for look-ahead scan on road surface [6,28]. Moreover, Magic Body Control (MBC) developed by the same company in 2013 has the Road Surface Scan function with a stereo camera.…”

In this paper, a Proportional-Integral-Derivative (PID) controller tuning scheme by Initialized Model Reference Adaptive Control (IMRAC) for a Lower Limb Exoskeleton (LLE) is presented. Mathematical expression of the LLE structure is determined using Lagrangian and Kirchoff's equations. The transfer function of the structure based on the physical features of the links, and actuators is established under Range of Motion (RoM) condition. The PID controller of the LLE is tuned in a closed-loop control system using Ziegler-Nichols (Z-N) for initializing parameters of IMRAC. Adjustment mechanism is a gradient based method for real-time adaptation of tuned PID controller. A Lyapunov function has been applied to confirm the stability of IMRAC. The proposed IMRAC shows faster convergence in comparison with conventional non-initialized model reference adaptive control. It can be ascertained the proposed tuning scheme is applicable for real-time tuning of PID controller of LLE.

“…These actuators can be of various types, such as pneumatic actuators, hydraulic actuators, and magnetic or electromagnetic actuators. The control force, managed through appropriate controllers, is essential to achieve optimal performance of the semi-active and active suspension system [10], [11].…”

At the beginning of the paper, the quantities that characterize a dynamic system are presented. Based on them, the state equations of the dynamic system are obtained, a system that models an active suspension. The types of used controllers, their block diagrams and the influence of the adjustment parameters on the process are reviewed. Next, numerical applications are made for the study of vibrations on models with 2 degrees of freedom, for an active suspension equipped with PID and LQR controllers. These controllers, as well as the simulation of the two systems, passive and active, were modelled and simulated using MATLAB/Simulink software. The numerical results obtained after the simulation are presented in the form of diagrams. In the end of the paper, it is concluded that the designed active suspension system can improve the ride quality by minimizing the displacement of the suspended mass.
