Advanced Control Technology of Industrial ProcessAdvanced process control has different kinds of methods, used for solving complex, usually multivariable control problems or discrete control problem.Adaptive Control: the parameters of the controlled system are uncertain

37、or changes with time, so the controller must find a way adapt to this kind of systems. For example, when an aircraft flies, its mass will slowly decrease as a result of fuel consumption. The speed control system in the aircraft should consider this in speed regulating. Adaptive control method has be

38、en used in mechanical systems without too much delay and systems with certain dynamic properties.Robust Control: this control method is used to deal with uncertainty. Robust control methods function properly as long as uncertain parameters or disturbances are within some range. This method aims to a

39、chieve robust performance and stability when there is modelling errors.Model Predictive Control: or MPC, has been in use in chemical plants and oil refineries. Model predictive controllers rely on dynamic models of the process, most often linear empirical models obtained by system identification. It

40、 analyses the historical data of the process and then predict the future input and output.Optimal Control: A control problem includes a cost functional that is a function of state and control variables. An optimal control is a set of differential equations describing the paths of the control variabl

41、es that minimize the cost functional. The optimal control can be derived using Pontryagins maximum principle (a necessary condition) or by solving the Bellman equation (a sufficient condition).40. PLC Application (Experiment)In this experiment we did in groups, I remember our team did an experiment

42、on traffic light control in the experiment panel.41. Motion Control Comprehensive ExperimentThe motion control system is used to control the position or velocity of machines, usually with the help of electric motors. Motion control is widely used in robotics, packaging and assembly industries. A mot

43、ion control system contains: a motion controller, a drive or amplifier, an actuator, feedback sensors and mechanical components.A motion controller: to set up the desired output. A drive or amplifier: to transform the control signal from the motion controller into a higher power electrical current o

44、r voltage that is presented to the actuator. An actuator: such as electric motor for output motion. Feedback sensors: to return the position or velocity of the actuator to the motion controller in order to close the control loops. Mechanical components: to transform the motion of the actuator into t

45、he desired motion, such as: gears, belts or rotational bearings.The interface between the motion controller and drives it controls is very critical when coordinated motion is required, as it must provide tight synchronization. Now interfaces capable of motion control include Ethernet/IP, Profinet IR

46、T (isochronous real time), Ethernet Powerlink, and EtherCAT.Common control functions include: Velocity control, position (point-to-point) control, pressure or force control.Servo: A servomechanism is an automatic device that uses error-sensing negative feedback to correct the performance of a mechan

47、ism. Servo applies only to systems where the feedback or error-correction signals help control mechanical position, speed or other parameters. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls positionthe operator does this by observation. By contrast the cars cruise control uses closed loop feedback, which classifies it as a servomechanism.42. Graduation Project
