    Abstract: A new multiresolution analysis (wavelet) assisted reinforcement learning (RL) based control strategy that can effectively deal with both multiscale disturbances in processes and the lack of process models. The application of wavelet aided RL based controller represents a paradigm shift in the control of large scale stochastic dynamic systems of which the control problem is a subset. The control strategy is termed a WRL-RbR controller. The WRL-RbR controller is tested on a multiple-input-multiple-output (MIMO) Chemical Mechanical Planarization (CMP) process of wafer fabrication for which process model is available. Results show that the RL controller outperforms EWMA based controllers for low autocorrelation. The new controller also performs quite well for strongly autocorrelated processes for which the EWMA controllers are known to fail. Convergence analysis of the new breed of WRL-RbR controller is presented.

On another front, a monitoring point for monitoring a plant error is registered in response to an operator request. A monitoring point is used as a key to select and register a main variable point having a strong correlation from the plant history data table. A statistical upper/lower limit function is defined on the basis of time-series plant data of monitoring points and main variable points. By referring to information in a table in which a limit value function is stored, the limit value is periodically matched with the content of a plant-data most-recent-value table A3. If the most recent value is outside the limit range, deviation information is stored in a determination result table A13.

  • Patent number: 7426666
    Abstract: Bit error patterns for high speed data systems are generated by randomly distributing a first error pattern of G bits, output from a group of substantially uncorrelated bit error generators, into a second error pattern of N bits, where G and N are integers and G is less than or equal to N. In one embodiment, G bit error generators produce a G bit error pattern per bit period. Each bit error generator operates at a prescribed bit error rate. A distribution element randomly rearranges the order and placement of the G bits produced during a single bit period within an N bit grouping. The N bit group corresponds to N consecutive bits of data with which the error bits can be combined. Each bit error generator can be realized by a linear feedback shift register or its equivalent. Different primitive polynomials and different lengths can be used for each linear feedback shift register. In addition, outputs from fewer than all the shift register stages are utilized to generate each error bit.

  • Patent number: 7392370
    Abstract: A method, apparatus, and computer instructions in a data processing system for processing instructions are provided. Instructions are received at a processor in the data processing system. If a selected indicator is associated with the instruction, counting of each event associated with the execution of the instruction is enabled. Functionality may be provided in the performance monitoring application for initiating the measurement of secondary metrics with regard to identified instructions, data addresses, ranges of identified instructions, or ranges of identified data addresses, based on counter values for primary metrics. Thus, for example, when a primary metric counter, or a combination of primary metric counters, meets or exceeds a predetermined threshold value, an interrupt may be generated. In response to receiving the interrupt, counters associated with the measuring of secondary metrics of a range of instructions/data addresses may be initiated.

  • Patent number: 7133727
    Abstract: A system and method for continuous online safety and reliability monitoring is disclosed. The method includes the steps of obtaining operating information about at least one of a plurality of instrumented function components, which are part of an instrumented function, and determining a probability of failure on demand for the instrumented function based on the operating information. In variations, instantaneous probability of failure on demand, online mean time to failure (MTTF), and online safety integrity level (SIL) are also calculated for an instrumented function. In other variations of the invention, alarms are reported to an operator based on the variance indicating the probability of failure on demand for the instrumented function is too high. In yet further variations, the system allows a user to predict probability of failure on demand values into the future based on hypothetical and/or future planned test times.

  • Patent number: 7099720
    Abstract: A method for identifying a control path of a controlled system, and more particularly to a method for identifying a control path in the presence of deterministic perturbations is described. At least one deterministic perturbation correcting signal is determined in a first identification process, and the perturbation correcting signal is stored in the form of a function. A control path of the controlled system is identified in a second identification process by adding to the controlled system the at least one stored deterministic perturbation correcting signal with a negative feedback. The method can be used with machine tools, production machines and/or robots which demand a high control accuracy and/or a high-quality control characteristic. In particular, perturbation effects due to slot latching in motors, in particular linear motors, can be minimized.
