Because of the severe consequences of failure of the control systems for power plants, algorithms must pay particular attention to the preservation of stability under adverse conditions such as severe disturbances and plant variability. In this paper, three algorithms are described which take into account the unique requirements encountered in power plant control.<>

This paper deals with the problem of input-output feedback linearization of nonlinear processes with unmeasurable disturbances which are not in the span of control input space. The proposed hybrid nonlinear controller which consists of a nonlinear static state feedback with a series of adjustable parameters and an internal model can achieve the purpose of disturbance attenuation and offset-free performance.<>

This paper presents a new bias-compensating least-squares method for the identification of continuous-time transfer function matrix model of multi-input multi-output (MIMO) systems. The proposed method uses the generalised Poisson moment functional approach for handling time derivatives and is applied to the identification of a laboratory-scale process which simulates industrial material transport control problems. Model validation results show the potentiality of the proposed method in practical applications.<>

This paper is broadly divided into three areas namely, the modelling of a high speed passenger lift system, identification of the sources of disturbance, and methods for improving the ride quality. A mathematical model representing the lift system was created initially and various tests were conducted on the actual system to obtain unknown parameters and also to verify the model. This model was then used to study ways of improving the ride quality. Some of the methods include active suspension technology and using modern control strategies to design a lift car velocity controller.<>

Replacing conventional gear-boxes by continuous variable transmissions (CVT's) can reduce fuel-consumption of spark-ignition engines (SI-engines) significantly. A possible approach to the control of this type of drive-train structure is discussed in this paper. Basically the plant dynamics are exactly linearized over the complete operating range using feedback linearization. Much attention is paid to the existence conditions for this nonlinear compensation. In a second step, as an application of the exact linearization approach, a "kick-down"-controller is designed which robustly stabilizes the nominal linearized plant.<>

This paper summarizes the main principles of a new, MATLAB-based Measurement and Control Tuning Toolbox (MCTB) which contains several facilities for controlling the most common data acquisition boards, control device calibrations, PID and feedforward control tuning and design of appropriate filters for measurement signal filtering. Some experiences are also described with the special emphasis on intelligent features that give the user information about the proceedings of the tuning work. The usefulness of the software always depends on the flexibility and simplicity of the user interface; we emphasize this importance.<>

This paper aims to describe the computational procedures to simulate car movements in a subway system connected to an AC supply network through a number of rectifiers. An iterative algorithm is proposed to analyze the AC busbar performances when under load variations, which can be caused by train speed changes (acceleration, deceleration, and stopover) and headway time between trains.<>

We develop an optimal predictive control for building heating, ventilating and air conditioning (HVAC) systems. Explicit inequality constraints on the input and on the output of the system are considered. A specific model-based recursive parameter identification and fault detection approach is described. Simplified physical modeling of the process establishes the model structure of an adaptive predictor to be used both for identification and control. The adaptive predictor is based on the estimation of the states. The parameters of the process are updated using a two-stage filtered instrumental projection method that ensures the promptness of fault detection. Fault detection is based on specific processing of the prediction errors and parameters of the predictor. Process diagnosis is ensured by appropriate use of the qualitative knowledge about the process. In order to increase the robustness of the fault detection scheme, additional test signals are introduced in the process.<>
