Output control signal

This study presents a force control approach for an EHA system using a combination of a feedforward-based PID (FPID) controller and a grey predictor (GP), shortened as grey predictor-based feedforward PID Controller (GPFPID). The FPID controller is used to drive the system to desired targets. Meanwhile, the GP predictor takes part in estimating the output in the near future to optimize the controller parameters in advance and to create a compensating control signal corresponding to the system perturbations, consequently, improving the control performance.

This paper presents a new methodology for the modeling and control of power systems based on an uncertain polytopic linear parameter-varying (LPV) approach using parameter set mapping with principle component analysis (PCA). An LPV representation of the power system dynamics is generated by linearization of its differential-algebraic equations about the transient operating points for some given specific faults containing the system nonlinear properties. The time response of the output signal in the transient state plays the role of the scheduling signal that is used to construct the LPV model.

A Novel Behavior-based Navigation Architecture of Mobile Robot in Unknown Environments This study proposes behavior-based navigation architecture, named BBFM, for mobile robot in unknown environment with obstacles. The architecture is carried out in three steps: analyzing the navigation problem to determine parameters of the architecture; designing the objective functions to relate input data with the desired output; and fusing the output of each objective function to generate the optimal control signal.

A systematic control design methodology is introduced for multi-input/multi-output stable open loop plants with multiple saturations. This new methodology is a substantial improvement over previous heuristic single-input/single-output approaches. The idea is to introduce a supervisor loop so that when the references and/or disturbances are sufficiently small, the control system operates linearly as designed.

Discussion: When connecting CHIP to the GND, the analog signal received from A/D Converter will send to single chip for decoding and output to 7 segment display? When sending the analog signal to the PC, the signal should be converted to digital format. As the result, this technique will be used when connecting the main unit to the PC.

In modern high-performance liquid chromatography (HPLC), computers in a broad sense are used in every instrumental module and at every stage of analysis. Computers control the flow rate, eluent composition, temperature, injection volume, and injection process. Detector output signal is converted from analog form into the digital representation to recognize the presence of peaks, and then at higher level of computer analysis a chromatogram is obtained. All these computer-based functions are performed in the background, and the chromatographer usually does not think about them.

The role of sensor systems for mechanical manufacturing is generally composed of sensing, transformation/conversion, signal processing, and decision making, as shown in Figure 1.3-1. The output of the sensor system is either given to the operator via a human-machine interface or directly utilized to control the machine. Objectives, requirements, demands, boundary conditions, signal processing, communication techniques, and the human-machine interface of the sensor system are described in this section. ...
