In this paper, we consider continuous-state systems and pursue a near-optimal policy through online learning. A new online reinforcement learning algorithm-MSEC (Multi-Samples in Each Cell) is proposed. The proposed algorithm combines state aggregation technique and efficient exploration principle, making high utilization of samples observed online. More concretely, we apply a grid over the continuous state space and partition it into different cells. Then, a near-upper Q iteration operator is defined to use samples in each cell and produce a near-upper Q function, whose corresponding greedy policy is efficient for exploration. MSEC is a totally model-free algorithm, which means no system dynamics is required during the implementation. It collects the system knowledge during the online learning. Based on PAC (Probability Approximately Correct) principle, MSCE can find a near-optimal policy in finite time bound online. To test the performance, an inverted pendulum is simulated and the results show the new algorithm is qualified for solving online optimal control problems.

This paper is concerned with the identification problems of linear parameter varying (LPV) systems with randomly missing output data. Since one local linearized model cannot capture the global dynamics of the nonlinear industrial process, the multiple-model LPV model in which the global model is constructed by smoothly weighted combination of multiple local models is considered here. The problem of missing output variables data is commonly encountered in practice. In order to handle the multiple-model identification problems of LPV systems with incomplete data, the local model is taken to have a finite impulse response (FIR) model structure and the generalized expectation-maximization (EM) algorithm is adopted to estimate the unknown parameters of the global LPV model. To avoid the problems of ill-conditioned matrices and high sensitivity of parameters to noise, the prior information on the coefficients of each local FIR model is employed to construct the prior probability of unknown parameters. Then the maximum a posteriori (MAP) estimates of the global model parameters are derived via the generalized EM algorithm. The numerical example is presented to demonstrate the effectiveness of the proposed method.

In the recent years haptic interfaces became a reliable solution in order to solve problems which arise when humans interact with the environment. If in the research area of the haptic interaction between human and environment there are important researches, a innovative approach for the interaction between the robot and the environment using haptic interfaces and virtual projection method is presented in this paper. In order to control this interaction we used the Virtual Projection Method where haptic control interfaces of impedance and admittance will be embedded. The obtained results, validated by simulations assure stability, stiffness, high maneuverability and adaptability for rescue walking robots in order to move in disaster, dangerous and hazardous areas.

This paper concerns a control problem for a 3-link planar robot moving in the vertical plane with only the rst joint being actuated by using the energy-based control approach. This robot is of underactuation degree two since the difference of the number of degrees of freedom and that of control input is two which is usually very dif cult to control. The control objective is to control simultaneously the total mechanical energy, the angular velocity and the angle of link 1 of the robot to their values corresponding to those at the upright equilibrium point, where all three links are in the upright position. The main contribution of this paper is to provide a global analysis of the convergence of the energy and the motion of the robot under the derived control law in a systematic way. By presenting a new property with its strict proof about the motion of the robot, without any condition on the mechanical parameters of the robot, we prove that the control objective is achieved for all initial states with the exception of a set of Lebesgue measure zero provided that two conditions on control gains are satis ed. Although there is no theoretical guarantee that there exists time such that the robot can be swung up close to the upright equilibrium point, the numerical simulation shows that this simultaneous control can be applied successfully to the swing-up and stabilizing control for a 3-link robot. This paper reveals the dif culty of the motion analysis of mechanical systems with underactuation degree greater than one.
