This paper presents innovative reinforcement learning methods for automatically tuning the parameters of a proportional integral derivative controller. Conventionally, high dimension Q-table is primary drawback when implementing algorithm. To overcome obstacle, idea underlying n-armed bandit problem used in this paper. Moreover, gain-scheduled actions are presented to tune algorithms improve ov...

A behavioral approach to the design of gain-scheduled controllers is presented. Plant models are considered to be black-box models obtained at nitely many operating points, and it is assumed that no analytical or empirical relations are known between physical parameters and the plant models. In this situation, it is suggested to interpolate in intermediate operating points, simply by interpolat...

For the problem of stabilization of mildly nonlinear systems with saturated control, a simple and computationally attractive method of designing a stabilizing gain scheduled output feedback is proposed. The resulting controller is characterized by an eecient use of the actuator capacity (\agressive" control), and is supplied with rigorously proven input/output performance bounds. In particular,...

In the hydraulic system, it is often that switch the control mode over from one to the other, such as from position to velocity or from velocity to force. In this paper, propose a flow calculation formula for the flow control valve in order to have an LPV system representation. Then, design gain scheduled controllers for the velocity and the force individually. During a switching mode, a contro...

In this paper, we propose a torque vectoring controller for an electric vehicle with two electric machines which drive the front wheels independently. The torque vectoring system includes a vehicle dynamics controller and a motor torque and wheel slip limiter. The vehicle dynamics controller is designed as a polytopic, linear parameter-varying (LPV) gain-scheduled controller. The LPV controller...

-Gain scheduling has proven to be a successful design methodology in many engineering applications. However in the absence of a sound theoretical analysis, these designs come with no guarantees on the robustness, performance, or even nominal stability of the overall gain scheduled design. This paper presents such an analysis for one type of gain scheduled system, namely, a linear parameter-vary...

More and more popular electric vehicles are excellent application platforms for steerby-wire (SBW) system. Handling stabilities and active safety are greatly improved when SBW is adopted in electric vehicle. The proposed new architecture of SBW electric vehicle is introduced, its dynamics model is built after the principle and structure. The algorithm achieves the yaw motion of electric vehicle...

This paper presents the three – level neutral point diode clamped inverter is used in a distribution static compensator (DSTATCOM), making use of the multi-level inverter advantages of low harmonics distortion and reduced switching losses. The pulse width modulation (PWM) inverter is employed as DSTATCOM compensating reactive power and eliminates the harmonics drawn from a non-linear load. A fu...
