Some remarks are given at the end. A nonlinear implicit self-tuning controller has been proposed Patete y col. The proposed algorithm is presented in this section as follows:. Then, to obtain the nonlinear model to wodld in the defined class Patete y col. In general, the class of nonlinear systems is defined as a SISO time invariant model 7 with the following structure Patete y col.

The generalized minimum variance control based on the concept of discrete-time sliding mode is proposed in Patete y market risk premium calculation. Polynomials C z -1 and Q z -1 are designed, so that the error signal ekdefined as 13vanish:. Using the Diophantine equation Chang y col. For the implicit self-tuning control, what is a real world example of a nonlinear function 9 is considered as a system with the same structure; however uncertainty parametric is taken into consideration.

Then, the parameters nonlineag the nominal control law 17 are estimated each sampled time.

The given algorithm is based on the idea of the discrete-time nonlineae mode control concept Furuta The slider-crank ls is a system what is a real world example of a nonlinear function can convert linear forces into rotational torque.

The slidercrank mechanism is used in many real systems like automobile engines. The slider is restricted by its direction of motion nonlinewr the x-axis and the center of the wheel, for the rotation axis, is fixed at the origin. Table 1 shows the model variables and Fo 2 the parameters of the slider-crank mechanism. Table 1 Variables of slider-crank mechanism. Table 2 Parameters of slider-crank mechanism.

A mathematical model for the slider-crank mechanism was proposed by Saitoh y col. In this work a new nonlinear model is proposed to represent the worrld dynamics of the slider-crank mechanism. The slider mass m p and the connecting rod mass are assumed to be one hole mass with COG nonoinear m p. Then, the force f applied to m p is equal to the exanple f applied at the end of the connecting rod. Based on Fig. As the variable to be controlled is the wheel angleqthen 29 should nknlinear only on q.

Whar the triangle relation 3031 is obtained:. To obtain a relation for cos fthe cosines law is used from Fig. The superior terms of 36 are insignificant numerically; therefore 36 may be rewritten in the following way:. From 31using 3840 is wgat. Finally, to obtain the translational movement equation, 313840 and 42 are substituted in 29 :. Equaling 43 and 47the first nonlineae no linear model for the slider-crank mechanism is obtained and presented in 48.

The obtained fhnction model 48 is a first order dynamical model, which is simpler than other models presented in the literature derived from the EulerLagrange technique, e. Yalcin However, this can a codependent and a narcissist be together 48 captures the natural nonlinear behavior of the real system showed in Fig.

First, the slider-crank mechanism model given in 48 should be transformed to a model represented polynomial terms as in 9. For that purpose the nonlinear terms in 48 are substituted by the respective Taylor Series. In this qorld only the first two terms of each series are considered, e. Then, to represent the model in the discrete-time case as in 9with T 0 representing the sampling-time period:.

Then from 17the generalized minimum variance control, to this particular model 49is In this mechanism some parameters may be measured and some others not; as are the cases for the viscous coefficients, where only an interval nonlibear values for that parameters are known. The parameter values in this functikn of study are show in Table 3. Table 3 Parameter values for the slider-crank mechanism model.

For the control design the x polynomials are chosen:. Finally, the sliding mode variable SMV for each case is presented in Fig. The generalized minimum variance control is not able to control the worlx to the reference because of the presence of uncertainty parameters, as it is shown in Fig. On the contrary, the self-tuning control is able to reach the objective and the output dynamic presets good performance in steady-state. In Fig. It is worth to mention that in the case where there are no parameter uncertainties, the generalized minimum variance control is able to control the system to the reference with good performance in steady-state.

A new nonlinear mathematical model was proposed for the slider-crank mechanism. The nonlinear model was rewritten into the particular nonlinear class of mathematical model what is a real world example of a nonlinear function in the discrete-time case. Generalized minimum variance nonlinear control and implicit self-tuning nonlinear control based on generalized minimum variance for the presence of uncertainty parameters were iis to regulate to a desired position the proposed nonlinear model.

The simulation results showed that the nonkinear self-tuning control is able to reach the angular position objective and the output dynamic presets good performance in steady-state, in spite of model parametric uncertainties and angle initial condition is far from the angular desired position.
