The vertical electric furnace is a multi-variable complex system, conventional control methods are used to control it, to need modelling and decoupling. In this paper, a new approach that automates the optimization of fuzzy control by using improved genetic algorithm is proposed for the vertical electric furnace. This algorithm is an on-line technique and is used to tune the parameters of the fuzzy controller and to eliminate coupling between the upper and the lower temperature regions of the vertical electric furnace in real-time. In the industrial control network, the experiments of controlling the vertical electric furnace are performed. The results show that this method is efficient and practical.

n jobs, each job i with a minimum processing time pi and a weight wi, have to be processed on a batching machine with capacity B. Minimization of total weighted completion time for single batching machine is a classical scheduling problem. Dijkstra's algorithm, the method to find the shortest path in a graph, is used to partition the jobs into batches. And it can get the optimal batches for a certain fixed sequence of the jobs for the batching machine. The batches also can be improved by the cyclic transfer algorithm that is the first time to be used to a batching machine. We give a comparison of the algorithms to the MRLC algorithm in the last part to prove the quality of the cyclic transfer algorithm. And the improvement of the cyclic transfer is over 1 percent.

There are many internal model control methods for the system with non-minimum phase zeros and time delays, but the decoupling result is not satisfied and the controller design is complicated. In order to solve these problems, a new decoupling IMC method is proposed. Non-minimum phase zero problem can be solved easily and if there are several different time delays in the system, the model of the system needn't to be converted to approximated model. As to parameter optimization of filter, the improved ISE index and NLJ algorithm were adopted to optimize the parameter of the filter. The simulation results have illustrated that this new internal model control method and parameter optimization method are simple and effective, and the decoupling result of two input-two output system is satisfied and has good tracking characteristics and robustness.

The control strategies of reconfiguration and obstacles negotiation are the intensive topic in the filed of leg-wheel hybrid robot. Based on the analysis of structure characters of leg-wheel hybrid robot and the disadvantage of early control method, this paper proposes a new reconfiguration control method in rough terrain and an auto-control method to get over channels, ridges etc. These control strategies are experimented in a six-leg-wheel hybrid robot which is designed by Shenyang Institute of Automation, and the results show that these control strategies can be effective used in rough terrain.

Based on in-vehicle network technology and ECU (Electronic Control Unit), passenger car information integrated control system implements correlative real-time control of passenger car functions. ECU is the core of system function implementation. Currently, passenger car ECU is designed according to special function requirement. Passenger car model has diversity because of the difference of market requirement and technology level. Variety of function requirement causes high cost and problem of maintenance for ECU development and application. In this paper, component-based ECU design method of passenger car information integrated control system is presented. Based on the analysis of holistic function of ECU, ECU components of passenger car information integrated control system are designed. In order to implement “component-ECU-system” 3-level development mode, ECU component configuration method and process are put forward. According to the function requirements of WG6100ENH model natural gas city bus information integrated control system, the system ECUs are designed. This case verifies the efficiency of the method presented in this paper.

This paper presents algorithms for vision-based detection, tracking and trajectory generation of vehicles in simple video sequences of traffic scenes which are registered by a stationary camera. Processing is done by three steps: improved vehicle detection method, faster tracking algorithm and new vehicle trajectory generation technique. Vehicles are viewed as rectangular blocks with certain active action. The propounded method is based on the correspondences between regions and vehicles, as the vehicles moving through the video sequence. The vehicle trajectory generation technique, used for gathering statistical traffic data for analysis in vehicle flow detection, is also described in detail. Experimental results from highway scenes demonstrate the effectiveness of the vehicle detection and tracking method.

In this paper, a method to coordinate multi-decentralized model predictive controllers(DMMPC), which is used as a strategy to control the integrated plant through decomposing the total system model into different functional sub-models, is proposed. Usually, an integrated plant is also called a large scale systems. The main aim is to relieve the expensive computation load and for improving the flexibility and reliability for operation. How to control and coordinate the possible dynamic coupling and constraints among subsystems has already become an important problem. In order to accomplish the overall objective, coordinating the relationship between optimizer located in upper layer and multi-decentralized MPC controllers located in down layer is a challenging work. A stochastic probability density functions(PDFs) coordination rule is applied to coordinate optimizer with decentralized MPC controllers in the hierarchical control structure. This approach provides the guarantee that local optimal solutions for dominant controlled variables approximate their global optimal solutions under considering uncertainties and interactions among subunits on closed-loop stability condition. As a study case, an integrated plant which consists of two subunits connected via other process and some intermediate tanks under severe constraints while considering maximization economic performance is used to demonstrate feasibility and efficiency of this framework.

To the positions of customer order decoupling point on leagile supply chain, according to the resource capacity of supply chain members, a kind of decision making model represented by CODP on supply chain are established. The decision making model was formally described in mathematical language to make it readily manipulated by computers through using the polychromatic sets. Then, using the reasoning matrix between the unit color and individual color of the polychromatic sets, the reasoning of decoupling points positioning was obtained. Finally, a case studies including two manufacturers enterprise on supply chain network is used to illustrate the proposed model and approach.

The common pseudorange measurement equations and their solution for satellite navigation are discussed. The errors in these pseudorange measurement equations computed with mathematical models will increase the load of computation and will usually lead to poor results due to change of conditions. In this paper the new pseudorange hyperboloidic measurement equations subject to height constraint for satellite navigation are developed and demonstrated. For these equations are all nonlinear, the methods of solving these nonlinear equations must be sought. The linearization of these nonlinear equations must be done before the iterative computation, but it is usually difficult to compute the Jacobian matrix of the nonlinear equations. The Unscented Kalman Filter (UKF) is presented for its ease of implementation and more accuracy for nonlinear equations. As a result, these nonlinear pseudorange measurement equations subject to height constraint solved with the UKF performs better than the common measurement equations computed with the iterative method. The conclusion is testified with experimental results last.

In this paper an Extended State Observer (ESO) based guidance law is proposed for hit-to-kill interceptors in the three-dimensional high-speed engagement. An approximate miss distance formula is given in this scenario. The nonlinear uncertainties and unknown target maneuvering are regarded as total disturbances of the kinematics, which are estimated by the ESO. With the estimation results as the compensation, the method of feedback linearization is adopted and the nonlinear kinematics is decoupled into two one-order subsystems. For each of the subsystems, a proportional controller is designed as the fictitious guidance command. The effectiveness of the ESO in estimation of the total disturbances and the performance of the guidance law are demonstrated through simulation.
