In this paper, the dynamic behavior of the nonlinear full-car model having active suspensions with nine degrees of freedom including driver, passenger seats and antilock braking system (ABS) is analyzed. The comfort analysis of a driver and passengers of the full car with active suspension model including all forms of nonlinearities is very rare in the literature. The literature also lacks the comfort analysis of the driver and passengers, while the car accelerates and decelerates during cornering. The nonlinearities in the proposed model include the dry friction nonlinearities of the suspension dampers and the geometric nonlinearities of the four corners of the car chassis. Modified adaptive NeuroFuzzy Takagi-Sugeno-Kang (NFTSK) control strategies are presented for the vehicle active suspension control to improve the ride quality, road holding capability and vehicle stability. Separate control strategy is used for ABS to avoid wheel locking and slipping for providing better roadwheel contact. The paper also investigates the coordination of active suspensions and ABS to further enhance the performance of the ABS control. To validate the performance of the proposed intelligent control strategies, the response of the vehicle nonlinear model due to road irregularities is evaluated using various performance indexes. The results are then compared with passive control to verify the performance of modified adaptive NFTSK control.

“…Some other works using a quarter car model have dealt with optimal control in [4], adaptive control in [5] or robust linear control in [6]. Suspension control problems have also been resolved using a half car model as in [7] using an optimal control, [8] multi-objective control and [9] decoupling strategies. In addition, fuzzy control is also interested by many authors.…”

Độ êm dịu chuyển động là một yếu tố quan trọng trong việc thiết kế ô tô. Có nhiều cách tiếp cận có thể được sử dụng để nâng cao đặc tính này, trong đó các nhà nghiên cứu Việt Nam và thế giới quan tâm đến hệ thống treo bán tích cực. Bài báo này giới thiệu phương pháp điều khiển cân bằng được sử dụng cho hệ thống treo bán tích cực với hai chiến lược điều khiển bao gồm bộ điều khiển cân bằng on-off và liên tục. Ý tưởng chính của chiến lược này là lực giảm chấn được điều khiển thay đổi sao cho có biên độ bằng với lực của lò xo nhưng ngược dấu. Điều này sẽ giảm gia tốc thẳng đứng của thân xe. Kết quả mô phỏng trên miền thời gian chỉ rõ rằng bằng cách sử dụng phương pháp điều khiển cân bằng, giá trị sai lệch bình phương trung bình của dịch chuyển thân xe, góc lắc dọc thân xe và gia tốc của chúng giảm từ 25% đến 50% so với hệ thống treo bị động.

“…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.…”

“…LMI conditions were also used in [10], with an H 2 control for rejection of white noise disturbances by means of state feedback. In order to reduce the number of sensors, output feedback was used in [11], where the controller gains were provided based on convex optimization with LMI constraints. These works have as common point the use of control design conditions based on Lyapunov functions.…”

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.
